BREAKING: Thomas Vermaelen set to join Barcelona

Football Express News understands that Barcelona are set to sign Thomas Vermaelen after reports on Sunday confirmed he was in discussion with the La Liga giants.

Barca are keen to improve their defensive options this summer after seeing veteran defender Carles Puyol retire from football in late May and they have already done so by signing Jeremy Mathieu from Valencia.

And, following a weekend of negotiations involving Manchester United, Arsenal and Barca; it is now understood that the latter are edging closer to a deal for Thomas Vermaelen after submitting a bid of £10m.

We understood early on Sunday morning that Mats Hummels had agreed to join Man United after Arsenal refused to allow Belgian Vermaelen to join their Premier League rivals.

Thus, allowing Barca to make contact with the former Ajax man and make a move.

The Catalan side had set their sights on Paris Saint Germain defender Marquinhos but after having a huge £34m bid rejected by the Ligue 1 giants; Barca instead pushed their interest to the 28-year-old.
