Borussia Dortmund have joined the list of clubs who are keen to sign Norwich right-back Max Aarons.
The 19-year-old's growing list of admirers includes Tottenham, Arsenal, Everton and West Ham as well as Bundesliga leaders RB Leipzig.
However, the majority of those interested would prefer to conclude a deal in the summer.
Norwich are understood to be willing to let Aarons leave Carrow Road this month for a fee of around £30m - with Spurs considering whether to steal a march on their competitors and potentially agree a transfer in the next three weeks.
Aarons joined Norwich's academy in 2016 and made his first-team debut in August last year.
He was a key member of the squad which secured promotion to the Premier League last season after winning the Sky Bet Championship.
Aarons has made 19 Premier League appearances so far this season with Norwich bottom of the table.
