'Liverpool won't spend big this summer, this squad can compete for Europe's top prizes for years'.
However, the Merseyside outfit got their revenge at the start of June after Liverpool FC were 2-0 winners against Tottenham Hotspur in the Champions League final.
But despite the huge income gains of UEFA prize money the strategy has not changed.
"His kind of a little bit dirty dressing-room talks I can not do, these things you say in the dressing room that I am not allowed to say in public". We can not spend every year in the same manner.

"I'm excited about having the first proper test", said the manager during a pre-match press conference at the IN venue on Thursday.
Rooney finished by saying he has great respect for Klopp and what he has done so far, not just in the Premier League with the Reds but also at Borussia Dortmund.
