Document 3: 2010–11 Celtic F.C. season: The 2010–11 season was the 122nd season of competitive football by Celtic. New manager Neil Lennon made considerable changes to the Celtic team for the 2010-11 season. He sold Aiden McGeady for a then Scottish record £9.5 million along with captain Stephen McManus and fan favourite Artur Boruc. 13 other players also left the club, this gave Lennon enough funds to re-build for the new season. He looked to sign talented, young, cheap, relatively unknown players, from smaller leagues around the world. This paid off with players such as Gary Hooper, Beram Kayal and Emilio Izaguirre all having excellent seasons and earning many plaudits. Lennon also signed several experienced players on free transfers. Charlie Mulgrew, Joe Ledley, and Daniel Majstorović all went into the first team. In addition to these Lennon also signed five other players, including Fraser Forster on loan from Newcastle who became first choice 'keeper and helped set a new SPL record for most clean sheets.

Document 10: 2001–02 Hibernian F.C. season: Season 2001–02 was a turbulent one for Hibernian, as the team had three different permanent managers during the season. Alex McLeish left the club in December to manage Rangers; Hibs surprisingly replaced him with star player Franck Sauzée, who retired as a player when he was appointed manager. Sauzee's brief tenure saw a long winless run in the SPL and domestic cup defeats by Rangers and Ayr United. The winless run in the league dragged Hibs into the fringes of a relegation battle, and Sauzee was sacked after just 69 days in charge. Kilmarnock manager Bobby Williamson was hired as Sauzee's replacement, and a brief winning run averted any danger of relegation. Earlier in the season, Hibs had been knocked out of the UEFA Cup in the first round by AEK Athens, but only after a dramatic second leg at Easter Road that went to extra time.
