Ex-Chelsea star Glen Johnson has backed Frank Lampard to succeed Maurizio Sarri.

The Italian has guided the Blues to a third-placed finish and the Europa League final, which will be played against Arsenal on Wednesday in Baku.

But Johnson, who played alongside Lampard, believes Sarri's future has already been decided.

“I do think the club have made their mind up already," the former right-back told talkSPORT.

“Sarri hasn't done a bad job, I just think there are a few personalities that are clashing at Chelsea.

“If they win the final, you'd say it's a positive season.

“But I don't think it's about the results, it's just the way they're getting the results."

On Lampard, who currently manages Derby, Johnson added: “I think Lampard will definitely be Chelsea manager one day, and it might be sooner than I anticipated," he said.

“Could he do the job? Now might be slightly too early and I'm sure Lamps would probably agree with that, but I definitely think he'll be capable of being successful as the Chelsea manager.

“I personally think it's too early, but I could also see it happening. It's exciting.

“I actually want him to get the job, I think he'd be great there."
