As with most, no to Ben Arfa. He's too inconsistent and seems to cause drama, often seems to have a pretty poor work rate. He'd be slotting in behind the forwards in our system and we already have Snodgrass, Ince, Aluko, Boyd and Quinn all able to play there, Brady too if Robertson plays left wing back. Tiote though... I've always thought he's a cracking player, and I'd take him in a heartbeat if he was available. He's struck me as similar to Vlaar, surprised a top 6 team hasn't taken him. A strong deeper midfield player, and perhaps one role we're a bit light on.
I always thought Frimpong was alright, but maybe not if he failed at Barnsley....free agent mind http://en.wikipedia.org/wiki/Emmanuel_Frimpong
Wasn't Ben Arfa fined for reporting for training overweight? Edit: Here it is; http://bleacherreport.com/articles/2134205-newcastles-hatem-ben-arfa-fined-for-showing-up-to-training-overweight
