4. Arsenal: Dayot Upamecano
The problems at Arsenal run far deeper than the football pitch, and indeed the backroom staff. Stories of absentee owners siphoning money out of the club, and the altercation between Granit Xhaka and the home fans at the Emirates Stadium, have left a sour taste in the mouth.
However, to keep it on the pitch, Arsenal has one glaring problem. And that is (surprise, surprise) the defence. Without the likes of Pierre-Emerick Aubameyang and Alexandre Lacazette banging in the goals on an almost weekly basis, it is no exaggeration to say that the Gunners could potentially be embroiled in a relegation dogfight. Therefore, a defensive solution is undoubtedly urgently required.
The answer could well be RB Leipzig's French centre-back Dayot Upamecano. The youngster has been exceptional in the Bundesliga this season under Julian Nagelsmann. A total of 3.5 ball recoveries per game, along with 2.9 clearances and an aerial duel success rate of 67% speaks to his immense defensive ability. Also, Upamecano is a supreme distributor from deep. He averages a pass accuracy of 88.3% with 3.6 completed long balls per game, along with over 50 short passes, and loses the ball less than once per game. Provided Unai Emery is still in the Arsenal hot seat by the time January rolls around, Upamecano could well be the signing that saves his job.
