When you have won 13 Premier League titles, fans start to expect more than topping the domestic table.
For Manchester United fans, Sir Alex Ferguson included, the obsession was always with being champions of Europe. Succeeding in the Champions League is no doubt the greatest achievement a football manager in Europe can claim.
Arsene Wenger of Arsenal, despite so much success domestically, has failed to get his hands on the big-eared trophy, coming closest in 2006 after losing to Barcelona in the final.
Ferguson won it twice with Manchester United while Jose Mourinho has also won it twice, although neither with his beloved Chelsea.
Louis van Gaal has only managed to get his hands on it once, but how does his record in the Champions League compare to the Premier League's best managers?
Here we take a look.
