Argentina coach Tata Martino describes his time with Barcelona as a career "blip".

However, he doesn't regret accepting the opportunity.

"I'm not the kind of person who goes from one place to the next, suitcase in hand. But at Barcelona, it was a bit like that. There was no time to stop and think. I have to be honest though and like Guardiola once said, when Barcelona call you, you cannot have any doubts.

"I am just being critical with myself about what happened when I was there. I left nothing at Barça, it was a blip in my career - it turns out that it happened in the most important place I have worked at," Martino said.
