Just watched a video of that guilherme arana we have been linked with.
He strikes me as someone that would struggle in the prem, he seems to have very small legs.
He strikes me very much of the "new type" full back who runs alot, looks to leg it up and down quick, but dosent have much substance in terms of quality pass/crosses.
Maybe its just because i am used to having Leighton Baines as our fullback for years and years, but i love a fullback who has a wand of left foot, not a hit it in and hope left foot
