Tottenham attempted to scupper Manchester United's deal for Donny van de Beek.
The Red Devils have agreed a £40m deal with Ajax for the Netherlands midfielder.
But the Mirror says Spurs made a late push to hijack the move.
United's chief negotiator Matt Judge sped up negotiations after hearing about his rivals interest.
Van de Beek reportedly told friends Ole Gunnar Solskjaer's desire to sign him helped convince him of a move to Old Trafford.
