Chelsea have been handed a massive boost as Diego Costa and Didier Drogba are set to be fit for the Arsenal clash, according to the Telegraph.

The Premier League leaders will make a short trip to the Emirates on 26 April as they take on the Gunners in the upcoming clash. The Ivorian striker started during the Blues' 1-0 victory over Manchester United at Stamford Bridge.

Drogba confirmed he picked up an ankle injury, which forced him to withdraw from the charity match on 20 April. However, the veteran striker has returned to training and has stepped up his efforts to make himself available for the weekend trip to north London.

Meanwhile, Costa last featured for Chelsea during his side's 2-1 victory over Stoke City earlier in April. He has been sidelined since then with a hamstring injury and was set to miss the key clashes against the 20-times English champions and the Gunners.

Jose Mourinho admitted the Blues top scorer will return to training at the start of this week during the pre-match press conference before the United clash.

"Diego is progressing very well. I think he has a chance for the next weekend. Our target was for him to play the last four matches. Arsenal is the sixth from the end, so if he doesn't play against Arsenal or Leicester [on April 29], it is not a problem because we were always focusing on the last four," Mourinho said.

The Telegraph reports claim the Brazil-born Spain international will be hoping to be fit for the Arsenal fixture. The former Real Madrid manager is hoping Costa could start against Arsene Wenger's side on Sunday.

Despite Mourinho's desire to start Costa against the Emirates club, the Portuguese tactician is not willing to gamble his star striker. His medical team will assess the 26-year-old's fitness and any concerns could see him start from the bench against Arsenal.

If Drogba becomes available for the selection, the Chelsea manager is likely to start with the African striker for the Gunners clash. This will see Costa drop to the bench. A victory over Arsenal and Leicester City on 29 April will see the Blues being crowned as the champions of England.
