MILAN, March 24 (Xinhua) -- AC Milan head Massimiliano Allegri said Thiago Silva could probably sit out his side's Champions League game against Barcelona due to a thigh injury.

The Brazilian defender picked up the injury in warm-up for the game against Roma on Saturday, which the Milan side won 2-1 at home.

"Thiago Silva has a problem on his thigh and I think it's impossible to have him against Barcelona on Wednesday," Allegeri said.

"We played a good first half today and conceded in the only occasion when Roma came forward. We came on to the field after the break with the real desire to turn things around and we achieved it."

Zlatan Ibrahimovic bagged a brace to wrap up the win.

"Ibrahimovic played a great game today. I think he is among the best players in the world," added Allegri.
