Arsenal boss Mikel Arteta was delighted with Kieran Tierney's performance for their FA Cup win at Sheffield United.

Amid claims he could be sold this summer, the Scot shone in the 2-1 triumph.

Arteta said, "He's been training incredibly hard though [the lockdown for] COVID-19, it's been a tough moment for him in the last six or seven months and to move here from a different city, a different football club.

"He is a kid with an incredible attitude and he is so willing to learn and to put in everything he has. He has a massive heart and I am delighted to have him in the team.

"He's a kid who is going to get better and better and better."
