Gignacas will have a duel with "Man Utd" © EuroFootball.com

Attacker Andre Pierre Gignac will miss Wednesday's Champions League match against "Man Utd."

The footballer, who has been in good sporting form lately, injured his groin in Saturday's French championship game against "St. Etienne."

Medics predict that Gignac will not be able to play for about two weeks.

In the "Ligue 1" championship, the 25-year-old Frenchman scored five goals in 18 games.
