Chelsea have been without some key players in recent weeks which was partly the cause of their recent struggles especially going forward and breaking teams down.

Christian Pulisic, a summer recruitment who has shown positive signs after a tough start to life has been one of Chelsea's most reliable players this season but he's been out of action for a couple weeks due to injury.
Fortunately, the player is back in training and is expected to start the crucial match against Manchester United of February 17, a match that could decide who finishes top 4 between Chelsea and Manchester United.
Another player that could make a return is Ruben Loftus-Cheek, a player whose excellent run was disrupted by an Achilles injury in friendly match last season. His skillset is something Chelsea currently miss. His direct play, link up play and goals is something Chelsea desperately need and the player could start from the bench.
This is a huge boost for Chelsea and fans can hope for a positive result against a Manchester United team they've already lost twice to this season.
Goodluck blues.
