Former Chelsea fullback Graeme Le Saux feels victory in the Capital One Cup can spark a Treble winning season.
Chelsea meet Tottenham tomorrow at Wembley.
"Football is very much about momentum and the Capital One Cup gives Chelsea an opportunity to put down a marker for how the rest of the season will go," he said.
"If Chelsea win they will get a huge amount of momentum from it but equally losing the final carries a lot of disappointment with it. I've lost an FA Cup final and although it was the end of the season it took me a while to get over that because you build it up so much that it becomes hugely significant for both sides and for the positive or negative effect on the remainder of the season."
