Sergino Dest's potential move to Manchester United was derailed by none other than John Murtough during the latter stages of the transfer window.
The USA international's time at Barcelona seemed all but up with Xavi deeming the defender surplus to requirements. The 21-year-old eventually sealed a loan move to Serie A titans AC Milan, with a £17.5m buy-out clause included.
For a time, United emerged as contenders for the right-back. Diogo Dalot, who has since had an impressive start to this season, wasn't a particularly strong option in the position while Erik ten Hag was happy to let £50m Aaron Wan-Bissaka leave altogether.
