Biglia would be a top class signing, really would. OK not in a position we necessarily need extra players but signing an argentinian International who pulls the strings, would be on a closer wavelength to Ramirez than some of the others and would improve the balance of the squad as well with Cork more than comfortable at right back and Clyne having played left back in the past.
A pacey, clever striker would be a good signing I think, especially on loan. I like Rodriguez but don't think he's the impact player we sometimes need. Not sure if Fernandez is the answer but a good loan signing in that position would go down nicely.
I'd be very happy with a further option in midfield - I've mentioned Redmond before and think we could pick him up at a good price. He'd add depth and has the potential to be very good + can play right, left or through the middle.
