Grimaldo played 47 times for the Portuguese Liga club last season – but fell out with management on the final day after being selected to play despite the expectation that he would sit out so he could travel to Spain. Mikel Arteta is keen to add to his Arsenal squad after a poor end to the season saw the Gunners pip rivals Tottenham for the final Champions League spot. He has already moved to secure the signature of Porto star Fabio Vieira, while Manchester City striker Gabriel Jesus has been confirmed. Now, he looks set to move for a new left-back given the injury problems surrounding first-choice Kieran Tierney. According to Ekrem Konur on Twitter, Arsenal have held talks with Benfica over a move for the Spanish defender. However, Barcelona, Juventus and Chelsea are also believed to be interested and could prepare a move for the player later in the window.

The Gunners have reportedly rejected a bid for Ajax playmaker Lisandro Martinez as they look to bolster their options. It has been a busy summer at the Emirates so far and Arsenal fans will continue to watch the club’s affairs with interest as they look to land the likes of Grimaldo.
