IF he wasn't made of glass, I would probably understand trying to renew him despite his poor technique and limited intelligence (which also manifests on the field not only in real life). But as he is also injured more than he is fit, this seems like a no-brainer to me.
Cut him loose. One more of Barto's gifts out of the way, proceed to the next ones.
One of the worst deals of all time. Still can't believe how much these clowns paid for this fraud, and even more ridiculous to think about renewing him. Get this cunt out of this club ASAP!
