Chelsea manager Jose Mourinho has praised the competitiveness of the Premier League following his return to England.

Mourinho took charge at Stamford Bridge for a second time last week after leaving the club in 2007.

The 50-year-old went on to coach in Italy and Spain after departing the Blues, but he believes that the English top flight is one of the toughest around.

"English football is the mother country of football, there's no doubt about that and the competitiveness is very high," Mourinho told Chelsea's official website.

"I don't enjoy very much winning 6-0, I don't enjoy too much playing a league where you know you are playing against one other team and you know this is about 90 points, 92, 96, 100 points, 100 goals, 110 goals, 120 goals. If you make a little mistake and you lose a match you are in big trouble because your direct opponent doesn't lose any matches, and it's the same for them.

"The season before last, Barcelona with the number of points they had would have won every league, and they finished second. The same with Real Madrid this season. It's a two-horse race and that's a big difference from English football."

Mourinho won two Premier League titles, two League Cups and the FA Cup during his initial three-year spell with Chelsea.
