Alan Shearer thinks Chelsea and Arsenal will struggle to win the Premier League title unless they spend more money between now and the end of the transfer window.
The Blues have already brought in reinforcements in the shape of Willy Caballero, Alvaro Morata, Antonio Rudiger and Tiémoué Bakayoko but Shearer thinks they are still short.
“Sir Alex Ferguson always said you have to strengthen when you are at your strongest,” Shearer wrote in The Sun.
“If his Manchester United side won the Premier League, Fergie used to sign two or three top players in the summer just to freshen things up.
“That is how you stay at the top for a sustained period of time.
“At Blackburn, when we won the title in 1995, we did not strengthen and were made to pay with a seventh-place finish the following year.
“I fear Chelsea might have made the same mistake this summer.
“Yes, they have signed some good players in Alvaro Morata, Antonio Rudiger and Tiemoue Bakayoko, but they started yesterday’s Community Shield without any of them.
“And they have also let six of last season’s title-winning squad leave, including John Terry and Nemanja Matic, with Diego Costa seemingly soon to join them.
“There is no doubt they look short, which showed in yesterday’s penalty shootout defeat to Arsenal.”
Chelsea lost to Arsenal on penalties in the Community Shield on Sunday but Shearer reckons the Gunners still need more bodies in the door.
“Away from Chelsea’s woes, I am no more optimistic about Arsenal’s hopes this season,” Shearer added. “It’s nice for them that they won yesterday — another trophy following their FA Cup success over the same opposition in May.
“But I still don’t think it gives them any advantage, psychological or otherwise, over Chelsea in the league.
“And it will hardly stop any criticism that will come towards manager Arsene Wenger and Arsenal if they stutter midway through the season.
“One positive I think they can take from the Wembley game is the performance of Alexandre Lacazette.
“He looked sharp, his link-up play was good and the ball stuck to him.
“The Frenchman will give them something different this season, going in behind, with a bit of pace.
“But Lacazette and yesterday’s goalscorer, Sead Kolasinac, are their only two signings this summer.
“That is not enough for the Gunners if they want to be challenging for the title, which is ultimately what their supporters want.”
