Winger Guerrero was first spotted by Coyle playing for Real Madrid Castillas, the reserve team of the Spanish giants, and took the opportunity to run the rule over him in America, playing him in both games.
He certainly had an impact in the first game when he set up one goal, won a penalty and scored himself. The news coming back was that he was very impressive.
It's a matter of wait and see now but it would not surprise me one bit if Guerrero became a Burnley player very soon although the asking price of £2 million could prove to be a stumbling block.
