Chelsea have confirmed that Demba Ba is eligible to face Saints in tomorrow's FA Cup third round tie, after completing his £7m move from Newcastle this morning.

The Senegalese striker has signed a three-and-a-half-year contract at Stamford Bridge and is likely to go straight into their squad for this weekend's match at St Mary's.

Interim manager Rafa Benitez has already indicated he would like to give Fernando Torres a rest, meaning Ba could be in line to start for the Blues.
