Manchester United and Arsenal are both reportedly interested in signing Monaco full-back Djibril Sidibe this summer.
L'Equipe reports that the lack of progress in his proposed move to Spain has alerted both United and Arsenal, who are considering an approach for the 25-year-old.
However, United boss Jose Mourinho is still looking for further defensive reinforcements, while new Arsenal manager Unai Emery has refused to rule out the possibility of a sixth signing of the transfer window should a good opportunity arise.
Should Sidibe arrive at the Emirates Stadium then it could open the door for Hector Bellerin to leave, although the Spaniard has said that he will still be at the club at the start of the new season.
Sidibe would also likely command a hefty fee as he still has four years remaining on his contract at the Stade Louis II.
