When it came to negotiations for this deal, Guardiola’s side opted for a different approach and are well-placed to avoid a repeat of the Sancho saga.
As well as a standard 15 per cent sell-on fee for the future sale of Diaz, City included a specific clause to deter Madrid from selling to United.
The Sky Blues will receive a huge 40 per cent sell-on fee in the event of the Spanish midfielder being sold to another Manchester club – a clause that could well have proved useful in the case of Sancho.
Diaz has made a total of 21 appearances for Madrid but spent last season on loan at AC Milan.
The 21-year-old shone in Serie A and helped Stefano Pioli’s side secure second place in the league standings.
Such was the success of this move, Diaz has recently agreed to head back to the club for a further two-year spell.
City will closely be following his development as a player and know that Diaz is a one former academy graduate United are unlikely to make a move for.
