Documents:
source: Bob Paisley
text: Bob Paisley Robert "Bob" Paisley OBE (23 January 1919 – 14 February 1996) was an English footballer and manager who spent almost fifty years with Liverpool as a wing half, physiotherapist, coach and manager. Due to his achievements as Liverpool manager, Paisley is one of the most successful English football managers of all time. Paisley and Carlo Ancelotti are the only managers to have won the European Cup three times. During his nine-year tenure as Liverpool manager, Paisley won honours at a rate of 2.2 per season, a rate surpassed only by Pep Guardiola. He is one of five managers to have won the English top-flight championship as both player and manager at the same club, the others being Bill Nicholson (Tottenham Hotspur), Howard Kendall (Everton), George Graham (Arsenal) and Kenny Dalglish (Liverpool), the latter as player/manager.

They did finish second in the First Division behind champions Derby County, in a record-tight season that saw the top ten teams separated by less than ten points. A defeat in the penultimate round against newcomers Middlesbrough cost Liverpool a ninth league title.

text: 1978–79 Liverpool F.C. season Liverpool F.C. won its 11th league title, with a record-breaking season. They amassed a record points total of 68, with Kenny Dalglish and Graeme Souness as commanding influences in the team that had the highest goal scoring ratio under Bob Paisley's management. Defensively, Liverpool conceded only 16 goals (just four of them at Anfield) and goalkeeper Ray Clemence kept a total of 28 clean sheets in 42 League matches. Disappointing for Liverpool was the early exit of the European Cup, losing to domestic rivals Nottingham Forest in the inaugural round; Forest went on to win the European Cup along with the League Cup, and were proving to be Liverpool's most fierce competitors as the decade drew to a close. This ended Liverpool's chances of taking three European Cups in a row, an achievement only Real Madrid, Ajax and Bayern Munich have ever succeeded in doing.

text: List of Liverpool F.C. players (1–24 appearances) Liverpool Football Club is an English association football club based in Liverpool, Merseyside. The club was formed in 1892 following a disagreement between the board of Everton and club president John Houlding, who owned the club's ground, Anfield. The disagreement between the two parties over rent resulted in Everton moving to Goodison Park from Anfield, which left Houlding with an empty stadium. Thus, he founded Liverpool F.C. to play in the empty stadium. Liverpool won the First Division title for the first time in 1901; since then, the club has won a further 17 league titles, along with seven FA Cups and eight Football League Cups. They have also been crowned champions of European football on five occasions by winning the European Cup/UEFA Champions League in 1977, 1978, 1981, 1984 and 2005. The club was one of 22 members of the Premier League when it was formed in 1992. They experienced the most successful period in their history under the management of Bob Paisley, who guided the team to 21 trophies in nine seasons.

It was Liverpool's first competitive game under the management of Joe Fagan, who had been promoted from the coaching staff to replace the retiring Bob Paisley.

text: 1995–96 Sheffield United F.C. season The 1995-96 season was the 107th season in existence for Sheffield United, during which they played in Division One for the second successive season. In the first half of the season events in the boardroom overshadowed those on the pitch until Mike McDonald completed a successful take over of the club. Following his arrival manager Dave Bassett resigned and was replaced by Howard Kendall who was provided with the funds to overhaul the squad. A large number of changes were made to the playing squad over the following months meaning the club used more first-team players in one season than ever before. Although struggling for much of the season the new arrivals brought about a late rally and the club finished a respectable ninth in the division.
