Arsenal are competing with Manchester United over sponsorship money.

The Daily Mail says the commercial rivalry between Manchester United and Arsenal is going to intensify after the Gunners' signing of a £150million five-year shirt sponsorship extension with Emirates which they're calling football's second biggest ever shirt sponsorship deal after United's Chevrolet agreement.

Both Premier League giants are now in negotiations with Nike for long-term renewals of their kit-supply deals.

There's the possibility of a multi-year £1billion Nike deal at Old Trafford. And Arsenal, confident of reaching United's £100m-a-year commercial turnover, will want their next shirt manufacturers agreement to be in the same ballpark as United's.
