Chelsea goalkeeper Petr Cech reckons his side’s resilience is the reason behind their emergence as potential Double winners.

Carlo Ancelotti’s side are on the brink of claiming the Premier League title on Sunday and can also take home the FA Cup trophy when they take on Portsmouth six days later.

And despite seeing his team slip up when well poised earlier in the season, Cech says his team have learned how to respond to setbacks and can keep grasp of their advantage.

“We are confident and we know that we shouldn’t lose two games in a row,” said the 27-year-old.

“We know that when something goes wrong, we always want to put it right the next game and so far it has worked well.
