Chelsea spent the early part of last summer's transfer window trying to sign Achraf Hakimi from Inter Milan, but their pursuit proved to be unsuccessful.
The 23-year-old wing-back had just enjoyed a wonderful title-winning campaign at the San Siro and was attracting interest from around Europe. Hakimi ended up completing a £60million move to Paris Saint-Germain, despite the Blues holding a strong interest in the Moroccan.
So far this season, Hakimi has featured 28 times in all competitions for PSG and has been ever so impressive under Mauricio Pochettino - including in their late 1-0 win against Real Madrid in the UEFA Champions League Round of 16 first-leg on Tuesday evening.
