The Jamaica under-23 international recently spoke to German newspaper Bild, and while he refused to name which club he sees as his ideal destination, he was unequivocal about the Premier League being his aim (h/t Anthony Jepson of the Manchester Evening News, via Goal):
Adrian Kajumba of the Mirror reported Chelsea and Arsenal are also in pursuit of the Leverkusen speedster, who will cost any suitor "in excess of £40 million" as his star continues to rise in the Bundesliga.
The 20-year-old signed a five-and-a-half-year contract when he moved to the BayArena from Belgian club Genk in January 2017, and WhoScored.com showed evidence he's adapted well to German football in the season since:
The Red Devils are likely to have funds left over from that summer miss and are already 15 points behind rivals Manchester City in the Premier League table, meaning winter recruits are bound to be sought.
Mourinho has taken to using Marcus Rashford and Anthony Martial on the left flank, while Jesse Lingard has been in fine form on the opposite side, but Bailey would bring another dynamic to the position.
The youngster operates largely on the left and boasts the kind of pace to make almost anyone in the United squad envious, not to mention fine footwork to go along with it as Leverkusen demonstrated:
Bailey also boasts a bolt of a left foot that makes him a big threat on goal, but there are questions as to whether he is the kind of winger Mourinho is looking to bring in.
It's no surprise to see dribbling and shooting are among the trickster's strengths this season, per Football Radars, although his rate of dispossession and pass completion could improve:
There's also the fact Mourinho holds a reputation for placing his faith in players in or nearing their prime rather than youngsters, and he already has two up-and-comers who can play the role in Martial and Rashford.
Leverkusen don't want to sell their star and are likely to do their best in holding out until the summer if they can keep their starlet until then, but Bailey's England dream may be the X-factor United need to force a winter deal.
