It was an afternoon that Calum Chambers is unlikely to forget anytime soon. Away at Swansea in the monsoon-like rain back in November 2014, the England international got torn to shreds by Jefferson Montero. The winger had too much pace for the Arsenal man, and inspired a 2-1 comeback victory for the hosts.

Whilst the 25-year-old has done well to put those scars to one side by forcing himself into a first-team regular at the Emirates now, there is still a feeling that he is very much a round peg in a square hole when playing at right-back. His lack of natural athleticism mean he isn't the typical modern-day full-back, and whilst he's a central defender by trade, the defensive side of the game when playing on the flank completely changes.

And that is exactly why Chambers will be hoping he has learnt from that nightmare of a few years ago, when he takes on another equally quick, but technically gifted winger in Brighton's Leandro Trossard, on Thursday night.

After enjoying an impressive cameo against Liverpool last time out, Seagulls boss Graham Potter insisted that the door is very much open for Trossard to make the leap from the bench to the starting line-up. He said: "He can do both, it’s just the right time, the right game. We are coming to a period where we need to use everybody."

And with the Gunners so defensively fragile this season, Potter may well be inclined to unleash the Belgian at the Emirates. As per Whoscored, the £15m man has averaged an impressive 1.3 dribbles and two key passes per game, whilst he hasn't been afraid to try his luck either, managing 1.3 shots per game too. If Chambers allows the 25-year-old to have a run at him one-on-one with space in behind, then the defender will have an incredibly long night.

The former Southampton man has made 1.6 fouls per game in the Premier League this season, and much of those have been for making tactical fouls after a winger has gotten past him. He has the perfect opportunity however on Thursday night, to show that he has well and truly learned from that fateful clash against Swansea all those years ago.

Meanwhile, Arsenal turning away from prominent managerial candidate due to financial reasons would be criminal.
