Manchester United and Arsenal are leading the race for Norwich defender Max Aarons with Bayern Munich and Borussia Dortmund also interested, according to reports.
The 22-year-old has two years left on his deal with the Canaries, who are set for a return to the Championship as they sit rock bottom.
The England Under-21 defender has previously stayed loyal to the Premier League strugglers amid past interest but could be heading for the exit this summer.
With Norwich relegation bound, their resolve could be tested when the transfer window opens and the club could look to cash in, according to The Sun.
