Borussia Mönchengladbach head coach André Schubert admits Thorgan Hazard and Raffael are in a race against time to be fit for Wednesday’s Champions League trip to Celtic.
Former Chelsea winger Hazard, the brother of Stamford Bridge favourite Eden, picked up a knee injury while on international duty with Belgium and is rated as a serious doubt for tomorrow’s Bundesliga visit of Hamburg.
Attacking midfielder Raffael is also struggling with a thigh complaint, although there was some good news for Schubert yesterday when defender Tobias Strobl returned to training after shaking off a similar problem.
Hazard started and scored in the 2-1 defeat to Barcelona in their most recent Champions League Group C outing, while Raffael also played against the Calalan club.
The pair each netted a hat-trick in the 6-1 play-off second leg victory over Swiss side Young Boys in August.
Schubert, whose side began the group stage with a 4-0 loss at Manchester City, said: “We are not quite happy with the course of the injury with regards to Thorgan. He was treated by the national team but to my knowledge, not intensively.
“We sent him for a MRI scan when he returned and we think it’s just a bruise, or an irritation.
“Now it depends on how quickly the irritation subsides.
“With Raffael, the question mark is a bit bigger and we are being a little more careful.
“But Tobias Strobl is now back training and we have to wait and see how his body reacts.
“If he trains without any problems then theoretically, he could be used on Saturday.”
