The Football Association is hoping UEFA will look favourably on its appeal to have England striker Wayne Rooney's three-match ban reduced.
Rooney is currently set to miss the group phase of Euro 2012 after being sent off in England's final qualifier against Montenegro for kicking out at Miodrag Dzudovic.
The Manchester United star's appeal against the suspension will be heard in Switzerland on Thursday, a day after he has featured in his club's UEFA Champions League tie against Basel.
Adrian Bevington, managing director of Club England, feels a strong case has been put together, which will also include evidence from Dzudovic.
"It's been going on now since the sending-off when we were away in Montenegro," said Bevington, with the FA hoping the suspension will be cut to two matches.
"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.
"As everyone knows, we have submitted an appeal. Wayne will attend the hearing - he will travel in after United's game on Wednesday night - Fabio will also be there to give evidence.
"I believe the evidence provided by the Montenegrin player, who was quite supportive of Wayne after the game, will also be part of our case.
"I don't want to say too much more about what our case will be because it would be inappropriate to do so before the hearing, but we go there, obviously, with the hope of at least getting some reduction in the suspension so Wayne can play a more fulsome part in the tournament, if possible."
Asked if he is hopeful of success, Bevington replied: "I genuinely don't know. Thankfully, we aren't overly-experienced in going to UEFA, it's not something that we do as an organisation too frequently.
"All we can do is go with the best legal advice that we have, and with the way that Wayne, Fabio and those of us involved present ourselves on the day and appeal to UEFA to look favourably on it."
