Jürgen Klopp has had a huge impact on the club's fortunes, lifting them to six wins in their last seven games and greatly improving the confidence and morale around the squad and the club as a whole.

He fielded a weakened team in the previous round as a youthful-looking side overcame Bournemouth thanks to Nathaniel Clyne's first-half strike, but they will be hoping for a smoother passage to the next round with the boss likely to field a stronger starting side in the 101st meeting between the two clubs.

Captain Jordan Henderson and striker Daniel Sturridge are expected to be in the travelling party after coming on as second-half substitutes in the recent win over Swansea City to make their first cameos under Klopp.

Jose Enrique and Jordan Rossiter both took part in Liverpool U21s' 3-2 loss to Manchester United on Monday night, but aren't expected to be in the squad whilst Jon Flanagan, who has been on the sidelines since the final day of the 2013-14 season, has been pictured back in training at Melwood but isn't expected to be back in action until the New Year.
Centre-back Jose Fonte could be involved for the home side after overcoming a knee injury - but Jay Rodriguez (ankle), Florin Gardos (knee) and Fraser Forster (knee) are all out.
