LONDON (AFP) - The English FA have hired an external legal firm to help with Wayne Rooney's suspension appeal. Rooney's appeal against a three-match ban, which is threatening to rule him out of Euro 2012's entire group stage, will be heard by UEFA on Thursday. He is currently due to miss matches against France, Sweden and Ukraine next year for kicking out at Miodrag Dzudovic in final qualifier. Adrian Bevington, managing director of Club England, told BBC Radio 5Live's Sportsweek programme that the FA contingent are determined to put together a strong legal case, so they have brought in outside help. "We have spoken at length with our own internal lawyers on this, and also we have been working with an external legal firm as well, who have a great deal of expertise in sports law," Bevington said. "Wayne will attend the hearing - he will travel in after United's game on Wednesday in Basel.
