El Tel wrote in The Sun: "Thereâ€™s little doubt their expensively-assembled squad looks light on strikers â€” and Defoe would be the perfect solution.
"But Iâ€™m not suggesting he could replace Fernando Torres. Far from it.
"Defoeâ€™s arrival would help their No 1 front man Torres become even better.
"I believe Defoe could take away the crushing burden on Torres to convert every half-chance into a goal, therefore freeing the Spaniard to turn on all his other wonderful skills.
"Thereâ€™s just too much expectancy on Torres to become Chelseaâ€™s replacement for Didier Drogba.
"But heâ€™s simply not that kind of player, whereas Defoe is.
"Yes, I know Defoe signed a new deal with Tottenham a few weeks into this season.
"But having spent much of last season on the bench at White Hart Lane, I thought Chelsea could and should have made a serious attempt to lure him across London to Stamford Bridge."
