Manchester United have sold the naming rights to their Carrington training complex to US insurance broker Aon.

The eight-year deal, thought to be worth around $230m (£150m), will also see the company's logo on the team's training kit.

The partnership is also expected to involve the branding of the club's overseas tours.

Aon's name is currently on United's first-team kit until Chevrolet start their seven-year contract in 2014.

United bought out their lucrative training kit deal with DHL at the end of last year.
