I've not see any highlights of Clarkson's performances in the last 2 years but when he was doing alright at Bristol City, I seem to recall him playing a deeper role.
For me, if he comes in, we still need 1 or 2 out and out attacking options to replace the quality of McFadden and Anier.
Regarding his freebie to Algarve, I think Clarkson has raked in more than enough cash for the club to be entitled to this.
