Milan have received a boost ahead of their Champions League clash against Czechs Viktoria Plzen as forward Zlatan Ibrahimovic returned to full training.

The big Swede had spent two weeks on the sidelines with a groin problem since being ruled out of their opening European enco-unter against Barcelona, which ended in a 2-2 draw.

Without Ibrahimovic’s return, Milan would be in a state of crisis.

Brazilian forwards Alexandre Pato and Robinho are both injured while attacking midfielder Kevin-Prince Boateng, whom coach Massimiliano Allegri favours in a role behind the front two, is also unavailable.

When Pato was injured a week ago he was replaced by teenage forward Stefan El Shaarawy.

The 18-year-old scored Milan’s equaliser in the 1-1 draw against Udinese and then started in the 1-0 victory over Cesena on Saturday.

Veteran Filippo Inzaghi is also working his way back from a cruciate knee ligament injury and has made two brief substitute appearances in the last two games.

However, neither of those two were included in Milan’s 25-man Champions League squad.

It meant that without Ibrahimovic, the club would only be able to call on Antonio Cassano and 18-year-old Simone Andrea Ganz, who has yet to play for the first team and having come through the club’s youth system, was only on the Champions League B-list anyway.

Cassano at least has had a run of five games as a starter since the beginning of the season and has played twice for Italy as well, meaning the oft-maligned forward has gradually recovered his best form.

“Cassano is doing very well. People spoke a lot about him in the summer because it seemed as if he would be leaving,” said Allegri.

“However, we’re very happy that he stayed because it was never our intention to sell him.

“We’re taking care of him and he’s repaying us.”

Milan will be expecting to take three points from this game against group stage debutants Plzen, who began their campaign two weeks ago with a 1-1 draw at home to BATE Borisov, leaving all four teams level on one point.
