Neven Subotic has revealed the work rate demanded by Jurgen Klopp at Borussia Dortmund, although he admits his side "cannot run like robots".
The defender, 24, joined the Schwarzgelben in the summer of 2008 from Mainz along with coach Klopp, and has gone on to form an integral part of the BVB first team in recent seasons.
Dortmund currently sit top of their Champions League group and one point behind Bayern Munich in the Bundesliga, and Subotic puts the club's success down to their tireless efforts in matches.
"We have a tactic that we always try to put on the pitch and we want to fill this tactic with life," he is quoted as saying by The Daily Mail.
"We cannot run like robots so we are just doing our job. Klopp wants us to do our job plus five or 10 per cent more to really do more than the other team."
Subotic has been linked with a move away from Signal Iduna Park, with Manchester United rumoured to be among the defender's admirers, but he insists that a move away is extremely unlikely.
"I wouldn’t move to any other club," he continued. "I'm still growing with this club at a very great rate where it would be silly for me to go somewhere and try to grow faster with a big chance of then maybe sitting on the bench."
Subotic has nothing but words of praise for Klopp, who has signed the Serbia international twice in his career, and claims the 46-year-old cares immensely about Dortmund and his squad.
"You go into a room and see people laughing and you know he is in the middle just being himself," he added. "He is very friendly, very funny but then as a coach he has that serious side too.
"He stands out in the way he gets people to want to be on his good side, everybody wants him to be proud of them because he does so much for us.
"You see him always working and thinking about this tactic and that. He puts a lot of work and effort in and we all try to at least match that, if not top it.
"He is very emotional because he is very heavily invested in this team. You can tell he cares so much that he acts on it. If something happens to a family member that we care so much about we would cry and for him it is kind of the same thing."
