Manchester United manager Sir Alex Ferguson relishes his team taking on 'jolly green giants' of Stoke City "We've got the jolly green giants coming to play against us tomorrow," Ferguson said on Friday. The biggest team in Europe. You can get yourself in a tangle about that because they are a handful at set-piece plays and long throw-ins, but you can't make a terror for yourself. Shawcross was plucked from the relative obscurity of United's reserves five years ago to emerge as one of the best centre-halves in the country, earning a call-up to Roy Hodgson's squad for the World Cup qualifiers against San Marino and Poland. The 25 year-old did not feature in either game but is targeting a first international cap in the friendly against Sweden next month. Shawcross joined United as a 15 year-old and made only two appearances in the Carling Cup but will face Ferguson as Stoke's captain, with Pulis insisting he can still improve. He said: "I'm not so sure Ryan would have played many games if you look at Nemanja Vidic and Rio Ferdinand. He's been given the opportunity here and sometimes you have to take a step back to take steps forward. I think Ryan would be the first one to say by coming here he's got the opportunity he might not have got because of the quality at Old Trafford.
