Yes, Dannie Guthrie played his debut in 2006 and had a few first team appearance then. He went to Southhampton on a load deal in 2007, did pretty well there. He submitted a transfer request to Rafa, and was sold for 2.5 mio.
Playing the similar position and similar age, I prefer him to Lucas. Of course, Rafa saw otherwise and let Guthrie go.
