Cork joined on loan, as did Guthrie - who were both very good for us when they came in, but the quality around them was pretty poor.
Don't think teams should be able to loan players to the same league. For example, when Adebayor was on loan at Spurs before he signed for them, he wasn't able to play against Man City who were both in the top4 at the time. It gave City a better chance of beating them than everyone else in the league.
