Mexico coach Tata Martino has declared his season in charge of Barcelona the worst of his career.

Martino took the reins at Barca for the 2013/14 season.

“From the results side it was not a bad year. We won a title (the Super Copa) and we played a final, but in Barcelona what matters is how many titles you win. However, I say it was my worst year because my contribution as a coach started and ended with the management of the team," said the Argentine.

Martino admits the changes he made to their playing style wasn't embraced by all.

“There were issues that my management had a short life and for me the clasico with Real Madrid was key, which we won 2-1 at home. The second goal was made by running into space - which Barcelona don't always do.

"But I knew that if there was anything I could add to the team it not preventing the forward players from running forward into space.

"Speed was going to make Barcelona more complete because when there were lapses of dominance of the rival team, it was good to drop back and go into space. That was carried out the following year by Luis Enrique."
