Yves Bissouma
The 25-year-old has been linked with multiple clubs (including Aston Villa, Tottenham and Chelsea) and Arsenal have been scouting the midfielder in recent months.
Bissouma’s price tag is, though, between €40m (£34m) and €45m (£38.5m), making him more expensive than Tielemans, despite having the same amount of time left on his contract. It means the Leicester star is the number one option.
