FSV Mainz 05 (2001-2008)
- Club reached the Bundesliga and the UEFA Cup for the first time.
- Relegated in 2006-07; Klopp stays on, but leaves after they fail to win promotion.
Borussia Dortmund (2008-2015)
- Guided them to 6th and 5th in his first two seasons having taken over a side that had finished 13th the previous season.
- Won two titles in a row, breaking records along the way.
- Reached Champions League final in 2013 before leaving in 2015.
Klopp’s record speaks for itself. And all that having built a team on youth and a lack of funds. Considering Dortmund finished outside the top six for four years before he went there speaks volumes for his impact.
He has an underrated commodity in that he is loyal and stays sticks around longer than most managers. Having patient and sensible people on the board helps, but that is also because they know of his importance to the team and see that he has a positive impact.
Relentless in their approach, the passion of his sides mirrors his own, which Hammers would love. Unfortunately, he appears to be taking six to seven months off from the game.
- Promotion to Serie A.
- Narrowly missed out on Serie A title by coming runners-up in first season then fifth the following campaign.
- Twice runners-up in Serie A.
AC Milan (2001-2009)
- Won Champions League in 2002-03, 2006-07 and reached another final in 2004-05.
- Won Coppa Italia in 2002-03.
- Led Milan to Serie A title in 2003-04.
- Won Club World Cup in 2007.
- Led the Blues to their first ‘proper’ Double in first season by winning Premier League and FA Cup before being sacked at the end of the following trophyless campaign.
Paris St. Germain (2011-13)
- Ligue 1 title win in 2012-13.
Real Madrid (2013-15)
- Won Copa del Rey, Champions League and Club World Cup in 2014.
Might want a different kind of challenge taking over a club that does not and does not expect to compete for titles. He probably knows what he is getting himself into at clubs with trigger-happy owners (see Chelsea and Real Madrid), but West Ham will not expect as much, so it could give him the opportunity to build something if he believes The Hammers can at least get near the Champions League spots. But will he want to?
Preston North End (1998-2002)
- Took over club struggling in third tier, kept them up then reached the play-offs the following campaign.
- Wins title to achieve promotion to second tier in 2000.
- Reaches play-off final a year later, but loses to Sam Allardyce’s Bolton Wanderers.
- Guides the Toffees to a Champions League place.
- Reaches FA Cup final in 2008-09, but loses to Chelsea.
Manchester United (2013-14)
- Reaches League Cup semi-finals and Champions League quarter-finals.
Real Sociedad (2014-present)
- Not been in the job long, but beat Treble winners, Barcelona, and led them to a 15th place finish – three positions above where they were when he took over.
Not a blip on his record with Preston and secured Everton as a Premier League force to be reckoned with after years of relegation struggles before he was appointed. So despite his travails with United, he would very likely get West Ham challenging for the top-six.
Upton Park faithful want mavericks, but if his managerial career is anything to go by, Moyes won’t. He is unlikely to leave Spain of his own accord anyway. But in terms of stabilising a club in the upper-reaches of the table, he would be a HIT
