Liverpool manager Jurgen Klopp set to make a surprise return to Melwood on Monday morning after undergoing appendix surgery.
The Reds boss, who was taken ill on Friday evening after training, was forced to miss the 2-2 home Premier League draw with Sunderland.
It was expected the German would spend time away from the club to recover from his operation, with training on Sunday being taken by Liverpool’s first-team backroom staff.
However, it is believed Klopp is keen to return to work as soon as possible and is hopeful of being back at Melwood in the morning.
If that is the case, he could face the media in his usual pre-match conference scheduled for Monday afternoon, and may still travel with the squad to London ahead of the fourth round replay at Upton Park.
Jurgen Klopp is under no pressure to make an immediate return and may yet decide he would be best served continuing his recovery at home.
In his absence from Anfield on Saturday, assistants Zeljko Buvac, Peter Krawietz, Pep Lijnders and goalkeeping coach John Achterberg oversaw Liverpool throw away a two-goal lead late on against relegation-threatened Sunderland.
After Tuesday’s trip to West Ham, the Reds have two further away games at Aston Villa on Sunday and in the Europa League in Klopp’s homeland against Augsburg the following Thursday.
