Manchester United manager Ole Gunnar Solskjaer will be sweating over the fitness of two first-team players ahead of the weekend.
The Red Devils face a daunting trip to West Ham United on Sunday, looking to make it four wins out of five at the start of the Premier League season.
Man United travel to the London Stadium with one task at mind, bouncing back after humiliation in Bern on Tuesday.
Solskjaer watched his 10-man side drop a 1-0 lead, courtesy of Cristiano Ronaldo, to lose 2-1 against BSC Young Boys in their Champions League opener.
But in the Premier League, Man United are fresh off a resounding 4-1 triumph over Newcastle United and currently sit top of the table.
There are still injury concerns within the squad, though, ahead of potentially the toughest test of the campaign so far.
Solskjaer has three known absentees through injury – Marcus Rashford, Alex Telles and Amad Diallo.
Rashford is continuing his recovery after shoulder surgery and could make his return to the pitch in October.
Telles has been sidelined all season after suffering an ankle injury in pre-season training and is still out.
Amad is battling a thigh problem, which denied him an enticing loan move to Feyenoord in the summer transfer window.
Away from the certain absentees, there is hope that Scott McTominay and Edinson Cavani will be ready to play a part in east London.
Solskjaer will hope McTominay is ready to feature to some extent after undergoing minor groin surgery.
The Scottish midfielder is back in training, but Sunday’s Premier League clash could come too soon for him to be involved.
Fred and Nemanja Matic are currently sharing the honours of playing alongside Paul Pogba in a double midfield pivot.
There are also question marks over Edinson Cavani’s fitness, but Solskjaer will hope to have him challenging Ronaldo for a striker spot shortly.
He’s missed the last two games due to a knock suffered in training but could be ready to return to the fray for the trip to West Ham.
It will be interesting to see how Solskjaer manages Cavani and Ronaldo – two players vying for that sole striker spot.
The Portuguese icon will likely keep his place after scoring three goals in his first two games back at Man United, with Cavani offering an option from the bench.
