Manchester United struck a training-kit sponsorship deal on Monday, the Premier League champions saying they believed it was the first such agreement in English football.

United said they had agreed a four-year contract with express and logistics company DHL. While the club did not give exact details, a source with knowledge of the deal said it was worth $66 million.

That is more than the Old Trafford team received in the early 2000s from a shirt agreement with Vodafone although it is less than the $130 million media reports have said their existing shirt deal with insurance brokerage Aon was worth.

United won a record 19th league title last season and their on-field success has been matched by strong commercial revenue figures.

In May, quarterly financial results showed there was a 30 percent rise in commercial revenue compared to the same period the previous year.

"This deal breaks new ground in the English game"

"This deal breaks new ground in the English game," United chief executive David Gill said in a statement.

"We are delighted DHL has chosen to pioneer training kit sponsorship with the club. Their global presence and international standing are a perfect fit for the world's most popular football club."

DHL, part of Deutsche Post AG, will see their logo appear on training kit worn by first, reserve and youth team players.

United host Tottenham Hotspur later on Monday, seeking to build on last week's 2-1 win over West Bromwich Albion in their Premier League opener.
