Boca Juniors want midfielder Wilmar Barrios to postpone a move to Tottenham until the January transfer window after Spurs stepped up their interest in him, The Independent on Sunday say.
The Colombia international reportedly has a release clause of just under £14.5m in his contract.
The Independent on Sunday say Spurs are keen to snap him up this summer but Boca are reportedly desperate to keep him for as long as possible.
The Sunday Express say Tottenham and Chelsea are both chasing a deal for Manchester United forward Anthony Martial.
Meanwhile, Jack Wilshere is set to leave Arsenal and West Ham are confident they will sign the midfielder, according to reports.
The Sunday Mirror say the out-of-contract Wilshere will move on after being told by new Arsenal boss Unai Emery that he could be a fringe player if he stays at the Emirates Stadium.
The Sun on Sunday say Arsenal will not increase a £100,000-a-week contract offer, which is reportedly 20% pay cut, and that West Ham believe they can sign him in a deal worth £130,000 a week.
And the Sunday Mirror say Michail Antonio is set to leave West Ham and is wanted by Crystal Palace.
