Inter Milan coach Jose Mourinho concedes they're strong enough to compete with the Champions League top four.

"When you look at this set of semi-finals it seems obvious these are very strong teams with immense technique, physical strength, stamina and mentality," he told Sky Italia.

"It's no coincidence Chelsea are playing their fifth semi in six years, while United and Barca are also regulars at this stage. A miracle happens sometimes in football, but usually the best emerges. That is why Inter will win the title, because they are the best team in Italy."
