Arsenal defender Calum Chambers looks set to have a medical at Middlesbrough ahead of a season-long loan, according to reports.

The 21-year-old joined the Gunners from Southampton for £16-million in 2014 and has since scored three goals and assisted three times from 62 appearances for the club.

Chambers scored during his side’s 4-3 defeat to Liverpool in their opening Premier League encounter.

Meanwhile, Boro have performed well on their return to the Premier League, winning one and drawing two of their three matches, including a goalless draw at West Bromwich Albion.

Chambers would further boost Aitor Karanka’s defensive options as Boro attempt to re-establish themselves as a top-flight club, according to SkySports.

Should he complete the move, Chambers could be in line to make his debut against Crystal Palace on September 10, when the Premier League returns after the international break.

Kick-off has been set for 16:00.
