Manchester United, the record 19-time English Premier League champion, agreed on a four-year contract worth about £40 million for delivery company DHL to sponsor its training apparel, according to two people familiar with the deal. The contract is the first time any Premier League club has sold rights to sponsor only its training wear. The agreement is worth about half the £80 million the team receives from principal sponsor Aon, said one of the people, who declined to be identified because the deal was not yet public. United declined to comment on the report. DHL, controlled by Deutsche Post, wasn\'t able to comment immediately.
