Zurich 1- milan1 ( Video highlight : Ronaldinho's goal )

A fright night for AC Milan ended with a 1-1 draw and a place in the last 16 of the UEFA Champions League after FC Zürich paid a high price for a single unfortunate challenge.

Ronaldinho penalty
Milan Gajić's superb 29th-minute free-kick for the hosts, who had enjoyed a shock 1-0 win over Milan at San Siro on Matchday 2, looked set to steer the eliminated Swiss champions to a repeat success. But a red card in the 63rd minute for Alain Rochat after he felled Marco Borriello in the area, meant a penalty which Ronaldinho gratefully converted to settle nerves as Milan advanced as Group C runners-up behind Real Madrid CF.

Early chance
Milan made a bright start and needed only seven minutes to create their first chance, with left-back Luca Antonini breaking down the flank to cross, Marco Borriello nodding the ball on and Pato meeting it with a volley which Johnny Leoni did well to smother. It was not a sign of things to come. Zürich's Adrian Nikci swung a left-footed shot just wide by way of reply and although his side needed longer to settle than the seven-times European champions, they were impressive when they did.

Gajić strikes
The hosts could easily have taken the lead in the 26th minute when Gajić threaded the ball past Milan's defence for Alexandre Alphonse to sprint clean through only to balloon his shot over the bar. Gajić made no such mistake three minutes later from over 25 metres, bending his free-kick around the Milan wall and just inside the left-hand post with Dida beaten at full stretch. It was a fair reward for Zürich's efforts and despite Borriello hooking a half-chance over shortly afterwards, Zürich were looking good for their lead. They might even have had a second shortly before the break when Onyekachi Okonkwo sent in a rising shot from the edge of the area, forcing a sharp save from Dida.

Milan switch
Milan, which had struggled in the final third throughout the opening 45 minutes, showed a little more bite after the restart. Fed by Clarence Seedorf, Ronaldinho drilled in a low angled shot from inside the area which Leoni kept out with a one-handed save. It was not enough for Milan coach Leonardo, who sent on Mathieu Flamini for Massimo Ambrosini to try and stir things up.

Ronaldinho levels
Things certainly livened up in the 63rd minute, when Seedorf slipped a killer pass through to Borriello in the Zürich area and the Italian striker was sent tumbling by Rochat. A red card for the Swiss defender swiftly followed and Ronaldinho gave Leoni no chance with the spot-kick, sending the keeper the wrong way. Suddenly, it was a different contest and Milan substitute Kakha Kaladze came agonisingly close to putting the visitors in front with a header from Andrea Pirlo's free-kick. To their credit, Zürich were determined to exit the competition heads high and they limited Leonardo's men to only half chances late on, but Milan had done enough to advance
