(Reuters) -Chelsea striker Liam Delap is back in training after recovering from a hamstring injury but will not be available for their Premier League home game against promoted Sunderland this weekend, manager Enzo Maresca said on Friday.

The 22-year-old, who moved to Stamford Bridge from Ipswich Town for 30 million pounds ($40.26 million) in June, picked up the injury during the 2-0 home win over Fulham in August.
