Manchester United Treble winner Paul Scholes believes Chelsea need to completely change their back four.
Scholes has also questioned Chelsea's goalkeeper options Kepa Arrizabalaga and Edouard Mendy as Mauricio Pochettino prepares to take charge.
"I think he [Pochettino] is going to have to buy a couple of centre-halves, possibly a right-back, possibly a left-back, a whole new back four," Scholes told Premier League productions.
"I'm not sure about either goalkeeper," he added.
'But I think going forward, I always look at a team and I'm excited when they create chances, I think adding a centre-forward to that, they're always going to create chances and if you've got a team who can score goals you've always got a chance."
