Philippe Coutinho is not available for Saturday's Premier League opener against Watford.

The Liverpool No.10 has been out of training for a week due to a back injury, meaning he will miss the trip to Vicarage Road and remains a doubt for Tuesday’s Champions League play-off first leg at Hoffenheim.

“He has back problems and was not in training since last Friday,” Jürgen Klopp explained at his pre-match press conference.

“So no, he is not available and is also a doubt – if he is not available for Saturday – for Tuesday, unfortunately.”
