Another extremely promising youngster from this summer's U21 European Championships who United could sign is Athletic Bilbao's ridiculously talented winger/forward Iker Muniain, who has been on the Red Devil's radar for years. He has been dubbed "the Spanish Messi" by the media and has also been heralded as "the next Ronaldo", too. To draw comparisons with two of the game's best players is of course a huge compliment and indicative of the talents at his disposal. United know all about the youngster as he was an integral part of the Bilbao team that tore them apart in the Europa League back in 2012. And they've been interested in signing him ever since, though he'd cost a whopping £32 million despite celebrating his 20th birthday only six months ago.
