Massimo Donati will return to face his former side, AC Milan, in the San Siro next Tuesday with a spring in his step after scoring Celtic's injury-time winner against Shakhtar Donetsk last night.

The central midfielder was left out of the starting line-up, but replaced the stricken Lee Naylor after 16 minutes and went on to score the decisive strike in his side's 2-1 win.

The Parkhead side now only require a draw against the Rossoneri next Tuesday to progress to the last 16 of the competition for the second successive season, but Donati insists they will not travel to Italy looking for just a point.

"You always must go into a match looking for the win," he said. "If you don't get the win, you take the draw. If you go looking for a draw, it can go wrong and you can lose.

"When we played against AC Milan here in Glasgow, it was a special match for me. Now, I am playing them for a second time and I have the chance to gain qualification from the group. I don't have anything to prove, though.

Donati was ecstatic with his late intervention. "To score the goal at the end was something superb and I won't forget that. Funnily enough, I had another chance just five minutes before I scored, but I didn't shoot because it was on my left foot. If I had, there is a good chance it would have gone out of the ground. Getting the three points was terrific because now we know what we need to do in Milan."

It was an eventful night, too, for Paul Hartley, who started the match in a holding midfield role but was shuttled to left-back when Naylor went off injured. He praised Celtic's never-say-die spirit which carried them to the victory.

"That was typical Celtic, especially in European games," he said. "We fight right until the very end every time and have great belief and spirit in the squad. We're always capable of scoring a goal at the death. Despite their goal, and seeing two of our players stretchered off, I don't think any of us ever thought that it was destined not to be our night."

Celtic were forced into another re-shuffle before the break when John Kennedy crumpled to the turf to be replaced by Steven Pressley. "We have a big squad and players can come in and do a good job. Massimo came off the bench and scored and Steven came in for his first game of the season," added Hartley. "Players coming in when others are suspended are part and parcel of life at a club. We wish John Kennedy all the best and hope he makes a quick recovery.

He's had a real struggle and has shown what a strong character he is in the past."

Hartley was cup-tied for the last 16 tie with AC Milan in March, but played a more active role in the 2-1 win at Celtic Park last month. "We will go and try to match them the way we did at Parkhead," he said. "It depends how the manager wants to set the team up, but we will not fear them. We know we have players in our squad who can go and win a game."
