Manchester City manager Pep Guardiola said on Friday that he will never coach Barcelona again as pressure mounts on current boss Luis Enrique after Barcelona’s loss against Paris Saint-Germain in the Champions League on Tuesday.

Guardiola, who won 14 trophies in four years as Barcelona’s head coach, believes his former side are still the best team in the world. Despite their 4-0 thrashing at the hands of Paris Saint-Germain in the first-leg of their Champions League last-16 tie on Tuesday, Guardiola backs Barcelona to fightback.

“There’s a lot of competition, the opposition are so strong,” said Guardiola. “I will never go back to Barcelona to be coach there. My period there is gone. Barcelona are still the best team in the world. It’s always a surprise because they are so, so good, but in football anything can happen. When you have dominated world football, it’s normal that the people expect you to keep up that level, but my advice to you, knowing Luis and the players a little, is not to talk too much, because they will be back and prove you wrong. They’ve done it over the years, dominating football for 10 years, and they continue to be the best team in the world.”

Enrique, who has Barcelona to two La Liga titles and the Champions League, is out of a contract at the end of the season, with his team also facing a battle overtake Real Madrid the La Liga title race.
