Question: Who was managing when Stan Willemse's old club won the champions league?

full_context: Document 1: 1985–86 Chelsea F.C. season: It was the first season under the management of John Hollins, who had previously been a member of Chelsea's victories in the 1970 FA Cup Final and 1971 European Cup Winners' Cup Final. On 1 January 1986 Chelsea were second, two points behind leaders Manchester United and in March the club were still in second, four points behind Everton with two games in hand. The two games in hand were lost 4–0 at home to West Ham United and 6–0 away at Queens Park Rangers. After gaining just 9 points from a possible 33 in the last 11 games, Chelsea finished 6th for the second season in succession.
Document 2: England national football team manager: Swedish coach Sven - Göran Eriksson became the first foreign manager of the team in January 2001 amid much acrimony; he helped the team to three successive quarter - finals in major championships. Italian manager Fabio Capello replaced Steve McClaren in December 2007, after England failed to qualify for Euro 2008. Capello's side endured a lacklustre performance during the 2010 World Cup, but the FA confirmed that he would remain in the role. However, Capello resigned in February 2012, following a disagreement with the FA over their removal of John Terry's captaincy. He was replaced, on a caretaker basis, by Stuart Pearce, before Roy Hodgson was named as Capello's permanent replacement in May 2012. Hodgson's contract finished on 27 June 2016 as England were knocked out of UEFA Euro 2016 by Iceland in the round of 16. Sam Allardyce was announced as his successor a month later, but subsequently left the role after just one competitive match. He was replaced on a caretaker basis by England under - 21 coach and former England international defender Gareth Southgate, whose position was made permanent after four matches.
Document 3: List of FA Community Shield matches: Manchester United hold the record for the most victories, winning the competition 21 times since its inception. They also hold the distinction of having the most appearances (30) and most losses (9). Although the Shield has had its share of historical moments -- from Eric Cantona's first career hat - trick in 1992, to Manchester United's first loss of 1999 ending a streak of 33 consecutive games without a defeat -- it has been dismissed as a ceremonial friendly that is not on par with other domestic honours in terms of prestige. Winning the Shield has proven to be an unreliable indicator of success in the forthcoming season. Since the establishment of the Premier League in 1992, only seven clubs that won the Shield proceeded to become League champions in the same season, the last being Manchester United in 2010 -- 11. Indeed, Gianluca Vialli was sacked only weeks after guiding Chelsea to the victory in the 2000 match, following a lacklustre start to the season. The current holders are Arsenal, who defeated Chelsea in a penalty shootout after a 1 -- 1 draw in the 2017 edition.

Document 5: Chelsea F.C.: In July 2003, Bates sold Chelsea to Russian billionaire Roman Abramovich for £140 million. Over £100 million was spent on new players, but Ranieri was unable to deliver any trophies, and was replaced by José Mourinho. Under Mourinho, Chelsea became the fifth English team to win back-to-back league championships since the Second World War (2004–05 and 2005–06), in addition to winning an FA Cup (2007) and two League Cups (2005 and 2007). After a poor start to the 2007–2008 season, Mourinho was replaced by Avram Grant, who led the club to their first UEFA Champions League final, which they lost on penalties to Manchester United.
Document 6: Derek Saunders: Saunders was a member of Chelsea's 1954-55 Championship-winning team. He was one of only two players to play in every game that season. Saunders' position meant that he rarely scored goals, but he scored a crucial one against West Bromwich Albion to put Chelsea 3-2 ahead after they had trailed 0-2; they eventually won 4-2. He stayed with Chelsea for a further four seasons, though they were unable to repeat their title success. He featured in the first Chelsea side to play in a European competition, the Inter-Cities Fairs Cup in 1958. A year earlier, he had played for the representative London XI side in the same competition. He made 223 appearances for Chelsea, and scored nine goals. Upon leaving the club in 1959, Saunders became the Head Groundsman at Vincent Square, the central London playing fields for Westminster School.

Document 8: Gary Chivers: A central defender, Chivers began his career with Chelsea in 1979, and remained with the club until 1983, a poor period in the club's history. He then moved to Swansea City, followed by spells with Queens Park Rangers and Watford. He settled at Brighton & Hove Albion, enjoying a six-year stint with the club from 1987. He spent the summer of 1993 playing in Norway with Lyn Oslo before playing out his career at Bournemouth, retiring from professional football in 1995.

Document 10: Tommy Logan: Logan was a member of the Chelsea side that reached the 1915 FA Cup Final. He was one of the few Chelsea players to get a positive mention in the Manchester Guardian report on the final for a few "dashing excursions" into the Sheffield half, he failed to score. By then, he was judged to be "an ideal centre half who showed judgement in his play", although in his early years he had been considered a forward and had a good scoring ratio for Falkirk. He was playing further back when capped by Scotland.
Document 11: Fred Sargent: Sargent was a right winger who played for Tottenham Hotspur between 1934–1935 making 109 appearances (93 league and 16 F.A. Cup) and scored 31 goals for the club.

Document 13: Stan Willemse: Born in Brighton, Willemse served in the Royal Marines during the Second World War, and began his football career with Brighton & Hove Albion before signing for Londoners Chelsea in 1949 for £6,000, a sum which helped fund rebuilding work at Brighton's Goldstone Ground. He earned a reputation as a hard-tackling defender whilst with the club, and formed the backbone of the team which won the League Championship in 1954–55, alongside the likes of Roy Bentley, Ken Armstrong, Eric Parsons and Derek Saunders, playing 39 games that season.
Document 14: David Jack: An inside forward, Jack started his senior career with his father's club, Plymouth Argyle, after the war.

He scored 15 goals in 48 appearances in all competitions. In late 1920 he returned to the town of his birth, signing for Bolton Wanderers for a world record fee of £3,500 (£ in 2020). He spent eight seasons with the Trotters, forming a formidable partnership with Joe Smith, and between them they scored more than 300 goals. While with Bolton, he made history by being the first person to score a goal at Wembley Stadium, in the 1923 FA Cup Final; Bolton won 2–0 and Jack earned his first medal.
Document 15: William Charles Williams: After employment as a gardener and labourer he joined the Royal Navy Boys Service in Portsmouth in 1895 and was promoted to Boy first class in 1896, Seaman in 1898 and Able Seaman in 1901.
