The only way Real Madrid are prepared to sanction a sale of Gareth Bale to Manchester United is if David de Gea is sold in part-exchange.
The Red Devils have been strongly linked with a switch for Bale over the past fortnight, with Louis van Gaal refusing to downplay rumours.
While Madrid have also tried to distance themselves from the speculation, a report claims they will sanction a sale of Bale to United on one condition - They can sign David de Gea.
The Mirror report: "The Spanish giants are ready to hand an ultimatum to the Red Devils by telling them that including De Gea will be the deal-maker.
"Real have identified the 24-year-old as the goalkeeper to replace long-serving veteran Iker Casillas. De Gea is in the process of taking over from Casillas as Spain’s No 1. and it is a matter of pride at the Bernabeu that the top Spanish keeper plays for Real."
While the prospect of losing De Gea is an welcome scenario for United fans to consider - until he signs a new contract, such a proposal from Real will remain tempting.
Money which was going to be committed to the Bale deal, which would be waived from the total fee, could be spent on a top class replacement for the Spaniard, and they would be getting one of the world's best attackers in exchange.
The problem is however this would only add to the lop-sided line-up at the club, with a strong attack, competent midfield, poor defence and outstanding goalkeeper. Lose De Gea and even adding Bale, and naturally there will be several exciting games at Old Trafford - but whether they will actually be as or more successful than the current team is another matter.
