The Everton defender was courted by Chelsea last summer.
The young defender was heavily linked with a move to Chelsea last year as they saw several bids rejected.
He has once again been linked this summer, with incoming Manchester City manager Pep Guardiola also thought to be an admirer.
Merson though believes he will end up at Stamford Bridge and go on to become one of the best defenders in Europe if he plays in a defensive three under Antonio Conte.
“I see Stones going to Chelsea personally,” he told Soccer Saturday.
“I think the way Conte plays with a back three, there’s nobody better in Europe that could play in the middle of a three [than Stones]. I don’t think there will be anybody better.”
John Stones' future is likely to rest heavily on who the next Everton manager turns out to be.
Roberto Martinez was sacked this week and the hunt is currently on for his successor at the club.
Should the Blues make an appointment that interests the defender, then there is every chance he will be willing to give it another year to see how things go under him.
Regardless of that, the Blues are in a strong position to keep Stones anyway given he is secured to a long-term deal at present.
