Chelsea may be about to force their London rivals Tottenham Hotspur into missing out on not one, but two right-back targets this summer.
Porto's defender Ricardo Pereira runs with the ball.
However, in order to stop a bidding war the two clubs could have come to an agreement on which defender each would target and a cheaper resolution for all concerned could have been achieved.
Unfortunately for Tottenham, that plan may well be scuppered by news from Don Balon that the Blues are closing in on a deal to sign Cancelo themselves.
While this would be a blow for Juve too, it may force the reigning Serie A champions to up their interest in Pereira and although the North Londoners could compete for the 23-year-old, they probably could not offer the same wages or prestige as the Old Lady.
It would leave manager Mauricio Pochettino with a selection headache at right-back, with the Argentine probably without Kieran Trippier for the Premier League opener against Newcastle United on Sunday due to an ankle injury, while having already seen Kyle Walker join Manchester City earlier in the summer.
Spurs are yet to make any new signings in this window - the only club in the English top flight not to have done so - and two options for arguably their most problematic position could now be about to pass them by as well.
