Spurs managed a 1-0 win in the first leg of their Champions League tie against AC Milan at the San Siro last night.
“I am very happy with how we played,” the Cameroon international said.
“Milan are a very good team who are doing very well in the Italian league but we came here and were very professional.
“It is not over yet as a team of Milan’s calibre have many match-winners in their ranks.
“We will have to be very professional like tonight to progress. It will be hard but we have the belief we can do it.”
