Jurgen Klopp has revealed Gini Wijnaldum was 'angry' over not being selected for last season's Champions League semi-final second leg against Barcelona.

The Dutch midfielder eventually came off the bench to score twice in a famous 4-0 victory that sealed Liverpool's spot in the final.

Speaking about his team selections to Sky Sports, Klopp said: "I have to judge the situation always in the moment. We had situations like in the Champions League last year, second leg when everybody told me that Wijnaldum was really angry that he didn't start.

"I tell the boys you don't have to be happy with my decisions, you just have to accept them and after the game, we can speak about it. But before the game, we cannot.

"If you are in a session and you're not happy but you train well, come after the game in my office on Monday morning and I can explain it.

"If you would say I am a friend of players, believe me, come matchday I am the friend of exactly 11 players. All the others have some things to criticise if you would ask them."
