Bayern Munich, Lazio, Sampdoria and Milan are battling for Chievo teenage talent Emanuel Vignato.
According to Sky Sport Italia, Bundesliga giants Bayern Munich have made their first formal offer for the creative midfielder.
The Brazilian-Italian plays for Italy at Under-19 level and will turn 19 next week.
He made his Serie A debut last season with 10 games, scoring one goal and contributing one assist.
There are some issues with the Bayern proposal, such as the fact it would not include his younger brother, Samuele, who is currently playing for the Chievo youth team.
Lazio, Sampdoria and Milan, on the other hand, would be interested in taking them as a pair and their parents would appreciate the stay in Italy.
