ARSENAL are chasing Ajax star Nicolas Tagliafico in a £20m deal – as Mikel Arteta searches for a new left-back.

The 27-year-old Argentine defender is one of the best players in his position in Europe, and wants a new challenge.

He has been watched by a number of clubs over the last few seasons, including Chelsea, Barcelona and Atletico Madrid.

The Gunners are understood to be keen on a left-back this summer, to allow Bukayo Saka to move naturally further forward.

Tagliafico is is open to a move to the Emirates, and believed to want to test himself in the Premier League next season.

The full-back has been touted around Europe, and his reps have had contact from clubs during the Covid-19 break.
