Robinho delighted with AC Milan thumping of Arsenal
The Rossoneri have a foot in the Champions League quarter-finals following their magnificent performance at San Siro.
"Certainly things are looking good, but we need the same grit in the second leg too," Robinho told RAI Sport.
"We cannot allow our opponents anything. Zlatan Ibrahimovic is an extraordinary player with his assists and tricks, so I am happy for him.
"We know that we have the quality to fight on all fronts and will try our best."
