Berra warns of a defensive barrier ahead
Wolves' man of the moment Christophe Berra believes Mick McCarthy's strikers must improve by 10 per cent against Sunderland this Sunday – to beat a 'world class' goalkeeper.
In-form Berra, who has been Man of the Match in the last two games, knows all about Sunderland keeper Craig Gordon from their time together at Hearts, but Sunday's clash sees the Scotland internationals on opposite sides for the first time.


Gordon, 26, moved to the Black Cats in August, 2007, for a cool £9million – then a British record for a goalkeeper – while 24-year-old Berra made the switch in January 2009 for £2.3million.
Like Berra, Gordon wasn't an overnight success, but is now proving his worth and the Wolves man is convinced it's money well spent.
The defender said: "Everyone knows how good Craig is, but he's just been unlucky with injuries. At £9million, they paid a lot of money for him, but if you see that boy in training, he pulls off unbelievable saves.
"Hopefully come Sunday, he'll let a few in for us. We maybe needed that 10 per cent extra against Manchester United.
"We know we'll have to be on top form to beat them – we'll have to take our chances and make sure we bury them, because he's a good keeper.
"He can pull off world-class saves as we've seen for Scotland before."
