Chelsea manager Rafael Benitez believes his side's showdown with Tottenham will be a decisive moment in the battle to qualify for the Champions League.
The Blues are slugging it out with Tottenham and Arsenal to finish in the Premier League's top four and the momentum swung back to Benitez's men on Sunday.
While Tottenham were forced to settle for a 2-2 draw with Everton, Chelsea secured a hard-fought 2-1 win over Sunderland which allowed the west Londoners to climb above Andre Villas-Boas's team into third place on goal difference.
Arsenal's recent resurgence has kept them firmly in the hunt as well, with the Gunners in fifth place two points behind Chelsea.
But Benitez is convinced the battle will be decided by Chelsea's clash with Tottenham at Stamford Bridge, which is still to be rearranged after being postponed this weekend as a result of the Blues' FA Cup semi-final against Manchester City.
"We knew that we had to win and especially because they (Tottenham and Arsenal) will continue winning," Benitez told Chelsea TV on Monday.
"The main thing for me is the big picture, so keep calm. We have a good team, if we perform at our level we can win against anyone.
"You have some bad games and good games but it will be the same for them.
"We have to carry on. We have one game in hand on Tottenham so if we can do well, especially against them, maybe it's a game that can mean six points."
