FC Porto vs Liverpool: Dejan Lovren misses training ahead of Champions League quarter-final second leg

The Reds hold a 2-0 advantage heading to the Dragao after goals from Naby Keita and Roberto Firmino at Anfield last week

Liverpool could be without Dejan Lovren for their Champions League quarter-final second leg after the Croatian centre-back missed training.

Alex Oxlade-Chamberlain was also absent despite returning to training in recent weeks following a serious knee injury suffered a year ago against Roma in the same competition.

Oxlade-Chamberlain featured for the Under-23s at the weekend, but the Porto match appears to have come too soon.

Captain Jordan Henderson, who was forced off in Sunday's 2-0 win over Chelsea with an ankle problem, did participate with his teammates on Tuesday at Melwood.

Lovren, who played in last week's 2-0 first-leg victory, would have been in contention for another start at the Estadio do Dragao, although he may yet travel with the squad when they fly out to Portugal later in the day.

Mohamed Salah has broken his recent goal drought, with his goal against Southampton followed up with a powerful strike to seal victory against the Blues, leaving his boss stunned.

“It blew me away,” said the Liverpool manager. “I didn’t think anything in that moment but I know I was really happy because I was in line with the ball and maybe I saw first that it would go in.

"It was a really outstanding finish and I don’t want to minimise that but I loved the first goal, too. I was immediately reminded of the 4-3 against Borussia Dortmund.

"Hendo instead of Milly and Sadio instead of Dejan, but good team play, good cross, good header. The performance was really good but you need the goals, and we got them.”
