The Premier League champions are currently on a £14m-a-year deal with insurance company AIG, but that deal runs out in June 2010.
On Wednesday United confirmed that Aon, a Chicago-based global financial services company, have won the race to become the club’s new shirt sponsor.
Reports says United have agreed a deal that could be worth £80m over four years, a record £20m-a-year.
United chief executive David Gill said: “We are delighted to be entering such an important relationship with a company of the stature of Aon and to have its logo adorn our shirts from the start of the 2010/11 season.
“We look forward to being closely aligned with the world leader in risk management, a firm which shares our values and is an exciting partner for Manchester United. Today’s announcement clearly strengthens our position as one of the biggest clubs in world football.”
The deal could become money well spent for Aon. United’s current shirt sponsor, AIG, jumped from 84 to 30 on Barron’s most respected brand list. AIG moved up to 47th most recognized brand globally after one year’s sponsorship.
