Arsenal hold an interest in young Derby County left-back Lee Buchanan this summer, as they look to invest in support for Kieran Tierney.

The Daily Mail report that Arsenal have an interest in Derby County left-back Lee Buchanan ahead of the summer transfer window.

Arsenal are obviously on the hunt for a left-back this summer, given they’re currently playing Granit Xhaka in the position to cover for the injured Kieran Tierney, and Sead Kolasinac seems to be on the way out.

The issue is that Tierney is one of Arsenal’s key players when he’s fit. That makes it difficult to sign a more experienced left-back, who would probably expect to be the first choice.

The alternative is bringing in a young player who would happily play a backup role at first, learning from and eventually competing with Tierney for the first-choice spot.

From that point of view, Buchanan could be a good choice. He’s just 20 years old and playing his first full season for Derby County, who are 21st in the Championship with a more-than-decent risk of relegation.

Even if Derby secure safety in the division, Buchanan is still likely to be tempted by the chance to step up to the Premier League, despite the probability it would be a backup role. He’s also in the final year of his contract, so shouldn’t command a huge fee.

Buchanan has made 36 appearances this season, including 30 starts, and he’s provided three assists.
