"Simeone is on one side and Mourinho on the other ... [A tactical battle] is to expected. These are perhaps the two best tacticians in the world of football. A tactical battle is normal," he told Andadolu News Agency.
"On or off the field, Mourinho is someone I regard and appreciate highly. As he says himself, he is a special coach. But we, too, have a very special coach. Perhaps he will even surpass Mourinho.
"So, it will be a very good game. Mourinho is a very special technically but Simeone is on his way to becoming the best technical coach in the world."
Mourinho re-joined Chelsea last summer following a spell with Real Madrid.
