Conte was in the stands at San Siro cheering on Milan for their Champions League 2-0 victory over Barcelona.
"At the start of the season I said Serie A had lost many great players due to the economic crisis, but that put the pressure on us Coaches to make up for it with ideas and hard work. Serie A is competitive and the Champions League proved that.
"I compliment Massimiliano Allegri on the perfect performance, but Juve, Lazio and Inter also did great things in Europe. In Italy there is great tactical organisation and any of the teams give you trouble. For example, tomorrow Siena will be well-drilled, enthusiastic and organised."
