Kenny Dalglish is a former striker and current manager of English side Liverpool. He was born and grew up in Glasgow, Scotland, and came up through the ranks of Celtic. He won several titles with Celtic. He played in three World Cups for Scotland and has the national record of appearances and goals scored.
In 1977 he was brought to Liverpool to replace Kevin Keegan. He was given Keegan’s famous no.7 shirt and quickly settled in to become a firm favourite with The Kop. After having won 5 league titles, 3 European cups and 4 League Cups, Dalglish became player-manager ahead of the 1985/86 season. That season Liverpool won the double. He guided the club to another two league titles and another FA Cup before resigning in February 1991.
Dalglish’s retirement was short-lived and he was appointed manager for second division side Blackburn in October 1991. He led the club to promotion to the Premier League already that season. In the first season in the Premier League Blackburn came 4th, the following season 2nd before winning the title in the 1994/95 season. The following season his position changed from manager to Director of Football and at the end of the season he left Blackburn all together.

In January 1997 Dalglish replaced Kevin Keegan for the second time of his career. This time as manager of Newcastle United. Keegan had helped Newcastle to promotion from the second tier to the first tier of English football, first as a player in the early 1980s, then came back and also did it as a manager in the early 1990s. Dalglish finished the 1996/97 season with Newcastle being runners-up in the Premier League and qualifying for the UEFA Champions League. The 1997/98 campaign was less successful and Newcastle finished 13th. The 1998/99 season had barely started when Dalglish was sacked from his position.
The following season Dalglish was back in Scotland, as Director of Football at his old club Celtic. He had recommended ex-Liverpool player John Barnes as manager. Barnes was eventually sacked in February 2000 and Dalglish took over as caretaker manager. He guided them to finish the season with the Scottish League Cup title. Shortly after Celtic terminated his contract with the club.

Ahead of the 2009/10 season Kenny Dalglish was brought back to Liverpool to contribute with the youth development and as an ambassador of the club. Manager Rafael Benítez left the club one year later and was replaced by Roy Hodgson. A disastrous start to the 2010/11 season had Hodgson quickly falling out of favour with the Liverpool supporters and a growing desire to let Dalglish take over. Hodgson did eventually leave the club in January and Dalglish was appointed caretaker manager. Things slowly started to turn around for the better and the club started climbing again. They finished the season in 6th place. Dalglish was given a permanent three year deal in May. Almost twenty years after he left the same position, Daglish is again a firm favourite with the Liverpool fans as he is rebuilding the club.

UPDATE: 23 June 2011
After a battle to get the Turkish FA to accept Guus Hiddink breaking his contract, Chelsea instead pursued and successfully appointed Porto coach Andre Villas-Boas to take over at Stamford Bridge.

Carlo Ancelotti was sacked as Chelsea manager shortly after the 0-1 loss to Everton.
Sources within the Chelsea ranks reveal they’re going after Dutchman Guus Hiddink. Hiddink is currently coach of the Turkish national team, a position he has held since last August.
Hiddink was caretaker manager of Chelsea the last three months of the 2008-09 season. In that period he lifted the FA Cup trophy with the club, before Carlo Ancelotti was appointed new manager. Hiddink was at the same time also coach for the Russian national team. He has also coached the national sides of Australia, South Korea and the Netherlands.

Guus Hiddink enjoyed his greatest success as manager of Eredivisie side PSV Eindhoven in the late 1980s and during a later spell between 2002-2006. Hiddink is a friend of Chelsea owner Roman Abramovich but whether they will succeed in making Hiddink break his contract with Turkey is still to be seen.

Sir Alex Ferguson is the manager of English side Manchester United, a post he has held since 1986.
Born in Glasgow, Scotland he spent his playing career with various Scottish clubs up through the 1960s/70s. Ferguson’s career as a manager started with a brief stint at East Stirlingshire, at the early age of 32. He then managed St Mirren between 1974-1978 before joining Aberdeen.
At Aberdeen Ferguson gradually turned an underachieving, but well-established club, into winning the Scottish Premier Division for the first time in 25 years. The club went on to have their most successful period with a further two league titles, 4 Scottish Cups, 1 League Cup and the 1983 UEFA Cup Winners’ Cup. After this several clubs were chasing Ferguson, including Rangers (one of the clubs he had played for), Tottenham and Arsenal. He rejected all of them. With the sudden death of Scotland coach, Jock Stein, Ferguson took the caretaker position leading the national team in 1985-86 including the 1986 FIFA World Cup. In November 1986 he left Aberdeen and Scotland for the top post at Manchester United.
Again Ferguson was at the helm of an underperforming team, where fans expectations and demands weren’t met. What he in 24 years has achieved at the club is history and Ferguson is the most successful football coach in history. Amongst United’s long list of triumphs under Alex Ferguson are 11 Premier League titles (after 26 years since the last league title), 5 FA Cups, 4 League Cups, 1 UEFA Cup Winners’ Cup and 2 UEFA Champions League titles. In fact the 1998-99 season saw them winning the treble (Premier League, FA Cup and Champions League). There have been a lot of speculation about when he might retire and who would be to replace him. However in his 25th season in charge of United he still appears to be at the top of the game. Ferguson also wrote a very interesting autobiography, which makes an insightful read into the great man at work.
