Barcelona Should Not Let Transfer              Target Mats Hummels Move to Man           United

In Mats Hummels Barcelona have at last been linked with a centre-back who befits a club of their stature, but he appears to be slipping out of their hands. 

The German Borussia Dortmund defender is on the Blaugrana's radar as they seek to fill a gap in their defence.

With Carles Puyol's retirement, there is a hole in their back line.

Gerard Pique needs a sensible new partner, with Javier Mascheranoshowing at the World Cup why Barcelona have been foolish to play him out of position for so long.

The Argentine belongs in midfield where he is a good player, rather than in defence, where he is merely adequate.

Hummels is a classy performer, a key part of the Germany defence that helped their side lift the World Cup this summer.
