The 21-year-old moved to Gelsenkirchen back in 2016 to join Schalke's youth side, and received his first Bundesliga appearance the year after.
He has made 75 professional appearances since joining Schalke and has generated interest from top clubs around the globe, most recently from the Premier League.
Initial Liverpool interest
It was reported by Sky Sports Germany on the 12th July that Liverpool has entered the race for the US men's national team player.
The transfer fee, if he joined Liverpool, is rumoured to be around €25 million.
The day before, 90min reported that Liverpool had 'stepped up their scouting of McKennie'.
However, McKennie told CBS Sports in the US that if he moves then he wants to do so to develop as a player and be guaranteed a starting spot, which could potentially rule out any transfer to Merseyside.
Further Premier League interest
Amid interest from Everton and Tottenham Hotspur for current Saints midfielder Pierre-Emile Höjbjerg, McKennie could be the perfect replacement.
As a box-to-box midfielder who has the ability to drive the ball forwards well, he would be a great addition to the Saints. Possibly the ideal landing spot for McKennie, Southampton have a strong reputation for developing young players.
A move to Southampton, Everton or Newcastle would likely guarantee that he would secure a starting Premier League spot, although that is something that is less likely to happen with Leicester.
However, a transfer to Leicester would see Weston McKennie feature in the Europa League, after the Tigers finished fifth in the division on Sunday.
