Former Chelsea coach Ray Wilkins feels Marcos Alonso could be a weak link.

He has become a key part of the side who have won their last 12 Premier League games.

Wilkins isn't certain the Blues can carry on their stunning form for the rest of the season but thinks they could improve in Alonso's position.

"Alonso has done well on the left but I personally think they can find better," he said on talkSPORT.

"(Victor) Moses has been revitalised on the right.

"Whether they can continue for the rest of the season remains to be seen.

"But for the moment they're doing well."
