The Liverpool players were all smiles at Melwood on Tuesday ahead of the second-leg of their Champions League quarter-final against Porto.

The Reds hold a 2-0 lead in the tie and they should be in confident mood after earning their fifth consecutive win with all three points against Chelsea on Sunday.

Adam Lallana was back in training after being absent for the last three games through injury and the midfielder could be considered an option at the Estadio do Dragao.

Dejan Lovren started the first-leg at Anfield after returning from injury but he was only given a place on the substitutes bench at the weekend.

The Croatian missed the Reds' last training session before jetting off to Portugal on Tuesday afternoon and could be a doubt for the travelling squad.

UPDATE: Liverpool's confirmed 21-man Porto squad

Alex Oxlade-Chamberlain and Rhian Brewster were both missing from training as they continue their rehabilitation with the duo unlikely to have a place in the squad.

The rest of the squad appeared in good spirits ahead of the tie as they look to seal their place in the semi-finals against either Barcelona or Manchester United.
