Chelsea head into the weekend looking to end a disappointing run of league form, with three points vital in their push for Champions League qualification. Rosenior delivered a positive update on Fernandez, who had missed recent matches, including the FA Cup win over Port Vale.

"Enzo has been with the group and has been training very, very well," Rosenior said. "So, it's business as usual in terms of selection for the game. His application has been fantastic."

The manager also provided updates on defensive options, with Trevoh Chalobah edging closer to a return after a spell out since the Champions League tie against Paris Saint-Germain.

"Trevoh trained today," Rosenior explained. "Not quite fully, it was modified training. We'll make a decision on him, but he's very, very close."

Club captain Reece James remains sidelined, however, with Rosenior admitting the right-back is still some way off a return following his last appearance against Newcastle United.

"Reece is a little bit further away," he added.

There was more encouraging news surrounding Levi Colwill, who is nearing a comeback after a long-term knee ligament injury suffered in pre-season. The defender has returned to full training and will now take the next step in his recovery.

"I'm hoping we'll see Levi before the end of the season," said Rosenior. "He's an outstanding player and a leader in the dressing room.

"Levi will play some minutes with the Under-21s tomorrow, which is fantastic for him. After a long-term injury, you need that rehab period. I want to make sure he is 100 per cent right before we consider him for the first team."

With key players returning and others close behind, Chelsea will be hoping the squad boost arrives at the perfect time as they prepare for a defining test against one of the league's top sides.
