Former Arsenal man Serge Gnabry has been one of Bayern Munich's star performers since making his debut for the Bundesliga leaders in 2018, but contract issues could pave the way for a return to the Premier League.
Manchester United and Liverpool are both keeping tabs on the German international's situation, with Gnabry's contract due to expire at the end of the 2022-23 season.
Liverpool strengthened their forward line in January with the signing of Luis Diaz from Porto, while Manchester United's window saw them send forward Anthony Martial out on loan to Sevilla.
