Southampton fullback Nathaniel Clyne believes they're capable of upsetting Chelsea.

Chelsea return to domestic action at the weekend against the Saints, after being dumped out of the Champions League last 16 on Wednesday night.

"We saw them play against PSG and thought they looked a bit tired. Hopefully, we can capitalise on that,' the 23-year-old told talkSPORT.

"We are fresh at the moment and, if we take the game to them, we can cause an upset.

"If we play the game we can play, it will be a good game, and hopefully we can get the points.

"It will be difficult - Chelsea are a good team with quality players, but we are up for the challenge."
