Ross has improved. He is a top player. I’m a big fan of Ross Barkley. Always have been," the ex-Blues winger told the Daily Star .
“He’s been a bit less spoken about because of Jack Grealish and James Maddison and Mason Mount. But he’s done a terrific job at Chelsea.
“The last two games, against Liverpool and Everton, he was brilliant. Absolutely fantastic.
“I’ve always thought he was a top player and I think he’ll be at Chelsea for many, many years.
“Now the challenge for Ross is can he keep doing that, can he be that player who drives Chelsea on to win trophies, like his manager was? I think he can.”
