Former Chelsea coach Ray Wilkins says they're missing their leaders.

He put Chelsea's recent woes down to the absence of John Terry at the back and Frank Lampard's goal-scoring contribution from midfield.

"When you lose those goals from the middle of the field, you have a massive problem," Wilkins said.

"Whether it is the club who spends money or Rafa who spends money, it has to be done because the season is coming to a rather rapid halt and we are not even at Christmas yet."
