Arsenal's season is not over says captain Robin van Persie ahead of FA Cup clash against Aston Villa This could still be a good season for us. We have the FA Cup to look forward to and the Champions League. We will all be giving 100 per cent to make sure we bring one of those trophies home, hopefully both of them. Let's all stick together and fight. Wenger is reported to have addressed the squad ahead of Sunday's FA Cup fourth-round tie with Aston Villa to reaffirm his belief in the side. On-loan New York Red Bulls forward Thierry Henry, whose goal beat Leeds in the third round, missed the United game with a calf injury, as did midfielder Mikel Arteta, but both could feature against Villa. There was yesterday some positive news on the recovery of full-back Bacary Sagna, who resumed full training with the rest of the squad for the first time since suffering a fractured right fibula during the defeat at Tottenham on Oct 2. With Andre Santos, Carl Jenkinson and Kieran Gibbs also sidelined, teenage defender Ignasi Miquel has been drafted into a makeshift backline. Barcelona-born Miquel, 19, has come up through the youth ranks at Arsenal, captaining the reserves before being handed his first-team debut in last season's FA Cup fifth-round tie at Leyton Orient. The young Spaniard, who has been asked to operate as a makeshift left-back, is hoping an extended cup run can fulfil a lifelong ambition. It is a dream to play at Wembley in a big final. First, we have to go step by step, but obviously if we can get to Wembley it would be a big, big thing for us," Miquel said. We have not won a title for quite long, so it would be great for us - but our next game is on Sunday against Aston Villa and we must focus on that. If we keep working and stay mentally strong we can get through it.
