Former Nigeria midfielder, John Mikel Obi, has urged the club to sign two top centre-backs this summer.
Mikel Obi made the remarks on talkSPORT ahead of the Blues Club World Cup final against Paris Saint-Germain on Sunday.
According to him, the current defenders in the squad do not match the quality of William Saliba and Gabriel Magalhaes at Arsenal.
I strongly believe that we do need another top centre-back next to Colwill, Mikel Obi said.
Tosin Adarabioyo is a good player, but he's not a Chelsea standard defender.
