​​Liverpool boss Jurgen Klopp has revealed that he had to resist the temptation to start Roberto Firmino during their 3-2 win over Paris Saint-Germain in their UEFA Champions League opener on Tuesday, insisting that starting Daniel Sturridge instead paid off in the best possible way.

Klopp's faith in Sturridge paid off as the striker opener the scoring for the Reds early on to give them the lead, though Firmino did eventually come on in the 72nd minute to score what was the winner in injury time.

"Yes, when you have Bobby Firmino available you actually always think: 'Come on, bring him in.' But it was nice to see how Daniel [Sturridge] performed tonight and he paid 100 percent back so that's so cool for him, for us, such an important sign," ​Klopp said post the game.

"Great performance of Daniel, to be honest. The three in midfield did an outstanding job but they only can do it when both the two wingers and -- how we played -- the No.9 is helping in all these situations to keep the formation compact. It was fantastic. I said to Daniel before the game: 'You are in the best shape since I know you, physical-wise, and now you have to use that.' And that's what he did. Super game, super goal," he added.

Liverpool have started the season brilliantly, winning their opening six matches of the season for the first time since 1961, while also scoring 43 goals in the UCL since the start of the last season, the most for any team in the competition.
