Michu is not the sticking plaster needed to sole our short term goal shortage. Earliest he could sign for a British club is when the window opens in January and then he will need time to get match sharp.
He's joining Union Langreo a club in the Spanish 4th tier who his brother manages... at least in the short term until / if he gets fit. Apparently his right ankle has totally gone, doubt he could cope with the physicality of the championship...
