Zola Back In Hospital After Surgery  (Sky Sports)

Chelsea assistant manager Gianfranco Zola has been re-admitted to hospital after suffering complications from gallstone surgery.

Zola initially had surgery last week and was not on the bench for Monday's FA Cup fifth-round defeat at the hands of Manchester United.

Maurizio Sarri's assistant had been expected to return for Thursday's Europa League last-32 second-leg clash with Malmo but Chelsea have told Sky Sports News that is now unlikely to be the case.

The club is not putting a timescale on his return to training and Chelsea's matchday staff.

Chelsea face big games in two competitions in the next four days, first defending a 2-1 lead over their Swedish rivals at Stamford Bridge.

They then face Manchester City in the Carabao Cup final at Wembley on Sunday, looking for a first trophy under Sarri and revenge for the 6-0 defeat in the Premier League earlier this month.
