UNITED have opened a spy dossier on Spanish wonderkid Sergio Canales. The Reds are among a growing queue of suitors tracking Racing Santander's 18-year-old attacking midfielder. It is understood that the Reds' European scout Martin Ferguson, brother of Sir Alex, was among those casting an eye over the new teenage sensation last weekend in Racing's match against Real Valladolid. He saw Canales score Racing's equaliser in their home El Sardinero stadium. His points-saver followed on from a two-goal display away at Sevilla in his previous match to kick off a sensational 2010 for the local player, who has had the Spanish drooling. The gifted midfielder with an eye for goal has inevitably already caught the attention of Real Madrid. The big spenders have attempted to nip in ahead of their rivals for Canales' signature with a deal but have yet to make an agreement. The player is out of contract at Racing in the summer and from the beginning of this year was able to open dialogue with interested parties. While he'd be available for nothing at the end of the season as a free agent, Real at least have noted that to stick around until then might be too late. Canales has been at the Santander club since he was 11 but it has only been this season when new boss Miguel Angel Portugal gave him his chance that he proved he had the quality for La Liga.But it is not just Real Madrid and United who are monitoring Canales, Chelsea, Arsenal, Barcelona and Bayern Munich are all in the hunt. But the words of Canales suggest that the 18-year-old is not quite ready for a move to a top club, despite reported interest. He said: Right now my preference is for Racing. They are the ones who have given me the confidence to play and make my debut at 18-years-old. Without ruling out anything, in the situation that I am in, I'm happy here. His father Angel insists the Canales camp won't have their heads turned by the interest developing in Europe. Various clubs have been in contact but we must take things step by step, he said. It's an important moment for Sergio. It is complicated, not only for economic matters. We have not yet decided anything. It is clear that Sergio must continue to play and at a big team that can be difficult.
