Espanyol accept they'll be powerless to prevent Aaron Martin from quitting for the Premier League in January.

The young left-back is the subject of major interest from Premier League giants Manchester City and Manchester United ahead of the winter market.

Sport says Real Madrid made an attempt for Aaron over the summer, before settling on signing Theo Hernandez from Atlético Madrid.

Now the youngster is wanted by England's top two clubs this season, with plans to move for the youngster in January.

And while he's tied to Espanyol until 2022, his €30m buyout clause is a snip at today's Premier League market rates.

The Catalans accept the final decision will now be left to Aaron, with the hope of a guaranteed start under coach Quique Sanchez Flores convincing him to stay.
