Jenkinson spent last season on loan at West Ham, who would like to keep the right-back at Upton Park, but Sunderland have made their offer early and are willing to pay the 23-year-old’s wages in full, according to the Daily Telegraph.
Arsenal are said to be unwilling to sell a player they regard as having a first-team future at Emirates Stadium, but Sunderland’s move is likely to spark West Ham – and possibly other Premier League clubs – into making approaches of their own.
Sunderland, meanwhile, could offload Santiago Vergini to Newell’s Old Boys, according to the Sunderland Echo.
The Black Cats are duty-bound to sign the defender in a £2million permanent deal after he made in excess of 20 appearances on loan from Costa Rican outfit Sport Uruguay de Coronado last season, but the Argentina international was dropped by Dick Advocaat towards the end of the campaign, featuring in only one of their final five games as a substitute.
Newell’s Old Boys, however, are said to be interested in taking the 26-year-old back to his homeland if they can raise the funds, either by buying out the clause from Coronado or buying him directly from Sunderland.
