Jack Grealish will become "an even better player" working with Manchester City head coach Pep Guardiola, says the first £1m player Trevor Francis.
The England midfielder left Aston Villa to join the Premier League champions for a British record £100m on Thursday.

"He's a wonderful talent. I just wish we'd seen him a bit more of him in the Euros," he told BBC Midlands Today.
"I would have thought Man City had made up their minds about Jack long before the Euros.
