Arsenal has been informed that they will have to pay €40 million (£34.7 million) in the forthcoming transfer market to sign RB Leipzig midfielder Christopher Nkunku.
The Gunners are currently prioritizing a permanent move for Real Madrid loanee Martin Odegaard, but Mikel Arteta is said to be looking at other playmakers if Odegaard's offer falls through.
Nkunku's future at Leipzig is uncertain, and he has been linked with a move to Arsenal.
However, journalist Christian Falk claims that a move for the 23-year-old will be "difficult," amid reports that he is unhappy under Julian Nagelsmann.
Speaking to Bild, Falk said: "Leipzig is a bit shaken at the moment, and so Nkunku is also on the out list. I would say it will be difficult because he is tied down (his contract runs until 2024) and has a €40m (£34.7m) market value.
"There are, of course, alternatives, Julian Draxler, who is available on a free transfer, or Julian Brandt, who is on the cut list at Dortmund. They are a bit easier to achieve, but from a quality point, they would, of course, be a club that would definitely be an upgrade for him."
Nkunku has seven goals and eight assists in 32 appearances this season across all competitions.
