If the first leg of this year's CONCACAF Champions League final taught us anything, it is that the current form of the two teams involved doesn't count for much. Pachuca came into the game slumping, UANL was firing - and somehow Los Tuzos got out of the match with an away goal and a tie. The out-of-form visitors even managed to score first; red-hot Tigres contrived to miss a penalty: the game finished 1-1.
The first leg wasn't much influenced by the teams' form preceding it, and the second leg will perhaps be even less so.
