There were a few worries about the club when this man left...
An integral part of the Liverpool team during the 1970's, Kevin Keegan was signed from Scunthorpe United for £33,000 in 1971, at the start of a second spell of success under Bill Shankly, which would continue under Bob Paisley.
He would find the net on his debut in August of that year in a 3-1 win over Nottingham Forest on the opening day of the season. It was a sign of things to come, as LFC History reports, Keegan never played in a single reserve fixture for Liverpool up until his departure in 1977.
There would be no trophies in his first season in a Red shirt but the second season saw him help the Reds to success both at home and in Europe. Liverpool would lift the 1973 league title and the UEFA Cup - with Keegan scoring twice in the first leg of the final at Anfield against Borussia Monchengladbach in a 3-0 home win. The Reds would lose the second leg 2-0 in Germany but it was enough to secure their first European trophy.
The following season, Keegan would play an integral part in the Reds winning their second FA Cup before Billy Shankly retired, with Keegan finding the net twice in a 3-0 win over Newcastle United at Wembley. They were two of his six goals, which included a semi-final winner against Leicester City on the road to the final.
The 74/75 season was arguably the worst for the player but Keegan managed to bounce back and help the Reds to more success under Bob Paisley. In 1976 there was another League and UEFA Cup success, before winning the League and European Cup the following season. Then Liverpool would let Keegan depart to Hamburg for £500,000 after scoring 100 goals from 323 games.
At Hamburg he would end up winning the Bundesliga title, lose one European Cup final to Nottingham Forest before lifting the trophy again in 1983 - and also became European footballer of the year twice.
After his playing days, he turned his hand at management, including Newcastle United who he once played for, leading them to runners-up in the Premier League. He took over the management of England but couldn't lead them out of the group stages at Euro 2000, and resigned after the last match at Wembley resulted in a 1-0 defeat at the hands of Germany. He would help Manchester City regain promotion to the Premier League in 2002 before leaving in 2004, and would return briefly to Newcastle in 2008. Unfortunately he couldn't lead them to similar heights and left the club after disagreements with owner Mike Ashley.
