Manchester City sign Aston Villa midfielder Jack Grealish

Manchester City have confirmed the signing of midfielder Jack Grealish on a six-year contract.

Grealish has joined the club after they paid a British-record fee of around £100m to Aston Villa.

He becomes the club's first high-profile signing of the transfer window, and there could be more activity.

The Cityzens are keen on landing a world-class striker to fill the void left by Sergio Aguero's departure.

Tottenham Hotspur's Harry Kane is the prime target, but they are reluctant to meet the £160m price tag.

They are prepared to stay patient in their pursuit, and could make another approach in the coming weeks.

Meanwhile, the Cityzens could enter the race for Lionel Messi after Barcelona confirmed his shock exit.

The Argentine was already out-of-contract, but he was fancied to sign a new long-term deal earlier this week.

The Cityzens were interested in Messi last summer, and they could yet pursue him and play him up front.
