Ronaldinho's convertion of a dubiously-awarded penalty cancelled out Karim Benzema's opener for the visitors as the stalemate left both teams a point clear of Marseille, who thrashed FC Zurich 6-1, at the top of Group C.

There was no revenge for Madrid for their 3-2 defeat to the Italians at the Bernabeu two weeks ago but they were the better side, particularly before the break.

It was all Real at the start of the first half as the visitors dominated, much like they did in the early stages of the home match, leaving coach Manuel Pellegrini believing they should have won.

"I don't talk about the referee's decisions, we played well in the first half and showed the right attitude," he said, declining to talk about the penalty.

"We had 16 shots (in the first half) and only one Milan player, (Alexandre) Pato, made life difficult for us. We were in control.

"The second half was more difficult in terms of possession but we did all right and at the end we had two chances that could have brought us the three points we deserved."

Milan's Brazilian coach Leonardo said a draw was probably the right result. "If we look only at the first half, Real played very well, they had many chances but in the second I was a bit disappointed because we deserved to win," he said.

"We had good possession, we created many chances and we had the possibilty to win. "Honestly I think yes, they had many chances in the first and it was more difficult for us, we didn't cover the pitch well but in the second half we had many more chances, even (substitute Filippo) Inzaghi had a good chance.
