Thomas Tuchel demands maximum commitment from even youth team players but succeeds in building a winning mentality, according to his former player Andreas Beck.
The German coach has made an impressive start to his tenure at Chelsea, winning nine of his first 13 games in charge and remaining unbeaten.
Chelsea advanced into the quarter-finals of the Champions League with a comfortable 2-0 win over Atletico Madrid on Wednesday night and they have risen to fourth in the Premier League off the back of several positive results.
This successful start came as little surprise to former Germany international right-back Beck, who was coached by Tuchel in Stuttgart's youth ranks.
