Arsenal transfer news
With the German international centre-back looking to have picked a move to Manchester United over Arsenal, the Gunners are now prioritising a deal for Carvalho.
Defence and midfield are known to be the main areas of concern for Arsene Wenger this season, and although he had held out some hope of signing Hummels, he will now focus on Carvalho instead.
The 22-year-old is a top class defensive midfield player who is valued at around £25m by his club, having also attracted some interest from Chelsea in recent times.
