Chelsea are hopeful that Cole Palmer can give them a major boost by declaring himself fit to face Arsenal at Stamford Bridge on Sunday. The forward has been out with a groin injury since September and his return to action was delayed when he fractured a toe in a freak domestic accident last week. That forced Palmer to sit out Chelsea's 3-0 win over Barcelona in the Champions League on Tuesday but there is optimism that his fitness issues are close to an end. The 23-year-old has trained with the squad this week and may be ready to play some part against Arsenal.
