Kieran Tierney has joined a growing list of reported Arsenal left-back targets this summer, after news of Brendan Rodgers’ potential departure.

With Nacho Monreal’s injury problems, his age, and the fact he’s running down his deal, it could be time to invest in a new full-back on the left-hand side. Let’s have a look at the options linked to an Arsenal transfer.

Arsenal reportedly sent a club official to watch Alejandro Grimaldo recently, and they’ve been scouting him for a while. The 23-year-old Benfica defender comes with a tasty €60m release clause which seems too rich for Arsenal, especially when you consider the host of clubs linked with the left-back who can also play on the wing.

As detailed by Sport Witness, Juventus, Manchester United, Borussia Dortmund, Bayer Leverkusen, Everton, Inter Milan, Atletico Madrid, Milan, Sevilla, Manchester City, and Real Valladolid all had scouts at the same Europa League game as the Gunners and no doubt some of them were there to watch Grimaldo.

However, Spanish outlet Mundo Deportivo wrote in February that despite previous reports other teams could be interested in a move for Grimaldo, Arsenal and Atletico Madrid remain the two best-positioned clubs for his signature.

Grimaldo is enjoying a very impressive season in Portugal, so he could be a good replacement for Nacho Monreal, particularly given his age. The Spaniard’s biggest strength is his passing, but he’s also a strong dribbler, crosser and he holds onto the ball well.
