There is something brewing at Chelsea "which isn't nice" as they look to to retain the Premier League title, says Alan Shearer.
The former Blackburn and Newcastle striker said Antonio Conte's Blues need two or three players to have a chance of winning the title - which he reckons Manchester City will win.
Shearer, who won the league with Blackburn in 1995, told BBC Sport: "The top seven already are nailed on, I don't see any surprise breaking into there.
"I think Everton will be sixth or seventh, and the rest we know.
"But there's only one team that can win it and [Manchester] City brought [Pep] Guardiola to the club to win the Premier League and to win the Champions League, and he has to win something this year.
"Jose [Mourinho] will feel exactly the same at Manchester United.
"Chelsea, I do sense as if there's something brewing there which isn't nice.
"They need to get in another two or three players, I think, to have a chance of retaining that title."
