Eintracht Frankfurt and Wolfsburg are interested in Jens Petter Hague, but Milan are only willing to sell the Norwegian and ask for €12m.
The 21-year-old arrived ahead of 2020-21 from Bodo/Glimt, after having impressed during the match between the Rossoneri and the Norwegian champions in the preliminary stage of the Europa League.
Milan reportedly paid €5m for the winger, but his market value has increased after his three caps for Norway and 24 competitive games for the Rossoneri.
Hauge contributed five goals last term, including three in five Europa League matches, but has struggled to establish himself in the line-up at San Siro.
Tuttosport reports the two Bundesliga sides are considering making a move, as both Frankfurt and Wolfsburg had their first offers rejected.
The newspaper claims Milan are not willing to let the Norway international leave on loan this summer and will not sell for less than €12m.
