"With one man down it was a hard situation at half-time because I was so positive about the opportunity we should still have", he said.
However, Coutinho has historically put up fine performances against Manchester City and he could play a crucial role coming off the bench for The Reds.
His eyes were on the ball and if he got a toe on it and was then taken out by the keeper, it may well have been a red card the other way.
The Brazilian, 24, needed eight stitches in his face after being caught by a high boot from Sadio Mane during the 5-0 win over Liverpool on Saturday. He took out Salah, Liverpool's most risky player, and threw in Alex Oxlade-Chamberlain, which meant all surprise was gone from the side's attack. It was courageous. Unfortunately, he is injured but hopefully, he will come back as soon as possible.
Klavan is easily the weak link in the visitors' defence and the likes of Jordan Henderson, Emre Can and Georginio Wijnaldum will have to be on their toes to keep him from being isolated.
The German also played down suggestions that Coutinho's failed transfer could have a lingering impact his mindset, saying the player had accepted the disappointment of not getting his move to Spain.
"He played twice for 15 to 20 minutes [for Brazil], so he could have played 15 to 20 minutes in the City game, maybe longer".
IN many ways, the latest round of Premier League matches defied the convention of the first three.
Mellor thinks Liverpool will make no mistake against Sevilla and should have 2016's Europa League final defeat at the hands of the Spaniards in their minds.
Goalkeeper Mignolet said: "We have to take the first 20 minutes and how we played before the worldwide break and take it into the next game".
City are unbeaten in 12 Premier League games, their best run under Guardiola, while Argentina striker Aguero is now the outright leading non-European goalscorer in Premier League history with 124 goals.
City did not look so smooth and lively going forward, that even disrupted the free flowing passing they're renowned for.
The Belgium midfielder was man of the match for their rout of Liverpool on Saturday. Mane scored in all three matches this season, picking up where he left off last season.
"Phil is a fantastic player, and hopefully we can use him as quickly as possible".
