Schalke are hoping to convince the 22-year-old goalkeeper to sign a new contract but his performances in Italy are attracting interest from elsewhere
Nubel could return to Germany as a European Under-21 Championship winner.
Given he has made his breakthrough at Schalke, the comparisons with Neuer have come thick and fast.
Not that they are anything new. Nubel was even nicknamed 'Manuel' by his former team-mates at Paderborn.
Speculation is now mounting that Bayern Munich are considering an offer for Neuer's heir, particularly as he has just one year left on his contract at Schalke.
Uli Hoeness has kept tight-lipped, insisting that it will be up to sporting director Hasan Salihamidzic to decide but the Bavarians will certainly be tempted to make their move now, given RB Leipzig and Atletico Madrid are said to have joined the race for Nubel's services.
