The 19-year-old has played a starring role for the Catalans in the opening months of the current season, but his first-team role looks set to be diluted from now on following the return of £75m ace Luis Suarez after his biting ban.
El Haddadi has been playing alongside Lionel Messi and Neymar, but even though he’s impressed his talent is unlikely to be enough to keep him in Luis Enrique’s XI.
This has opened the door for a temporary move with Arsenal keen.
Barca themselves are willing to ship out the teenager to boost his development, with regular action in the Premier League likely to be appealing.
Arsene Wenger is a long-term fan of the classy attacker, whom he has tracked for several years.
El Haddadi is seen as the ideal man to cover for the likes of Alexis Sanchez and the returning Theo Walcott, with the Gunners keen to challenge for domestic and European honours in the New Year.
