Leeds United striker Pierre-Michel Lasogga could be set to miss a number of weeks with a mystery illness after manager Thomas Christiansen refused to confirm whether the former Germany Under-21 international would be fit to return against Wolverhampton Wanderers on Wednesday [22 November].

The 25-year-old missed the 2-1 win over Middlesbrough – the Whites' first Championship victory at Elland Road since September – after falling sick prior to the visit of Garry Monk's side. Lasogga is currently on loan from Bundesliga side Hamburg and has netted five goals this term.

Speaking before Leeds boss Christiansen gave his pre-match press briefing Caleb Ekuban, himself back after three months out with a broken bone in his foot, said Lasogga could be out for "a couple of weeks", leading to questions over the long-term fitness of the ex-Hertha Berlin hitman.

"Everyone is okay," Christiansen responded coyly, according to the Yorkshire Evening Post, when questioned about the condition of his squad ahead of the trip to Molineux. "I said he was sick and we will see now if he will be able to come in or not."

Winger Stuart Dallas is available after also missing the win over Boro' with an ankle injury picked up while playing for Northern Ireland in their World Cup play-off against Switzerland, while Manchester United loanee Cameron Borthwick-Jackson is in contention after not being considering for the last four games due to an ankle issue.

"He [Dallas] is okay," the Leeds coach added. "He is fine and he will be with the team. [Borthwick-Jackson] is back."

If Lasogga is indeed ruled out for a sustained period then Kemar Roofe is likely to have an extended spell up front after leading the attack against Middlesbrough, a position he played for just the third time this season.

And Christiansen will have no hesitation deployed the former Oxford United man in that role again if needed.

"He has always had good games when he's come in as a striker," he added of the Leeds man, who has six goals this term. "Pablo (Hernandez) didn't start the last game at Brentford but when he came in, as well as Roofe, they changed that game – a game which from my point of view we should have won.

"They got another opportunity to prove their worth and did so perfectly. But everyone was good. "The defence were good and we showed the character I expected from the team. They proved that they have it again."
