Inter Milan's [ Images ] influential playmaker Wesley Sneijder [ Images ] is a doubt for Wednesday's Champions League [ Images ] semi-final second leg in Barcelona [ Images ] due to a thigh problem.

The former Real Madrid [ Images ] man, who scored in Inter's 3-1 first-leg win, came off at halftime in the 3-1 Serie A victory over Atalanta which sent Jose Mourinho's side top on Saturday.

"Wesley Sneijder has undergone a medical check-up which showed a muscle tweak in his left thigh," Inter said in a statement.

"The condition of the Dutch midfielder will be monitored in the next 48 hours."

The possible absence of Sneijder on Wednesday would be a big blow for Inter given he has been one of their most consistent players this season and expertly links midfield and attack.

Forward Goran Pandev and right back Maicon [ Images ] were not risked for the Atalanta game because of muscle tightness and a broken tooth respectively but are in line to be fit for the Barca game.
