@LDN : for the work permit, this ^ edit : oops, just have seen you weren't talking about the work permit. As for Subotic/Cahill, of course Cahill will be cheaper than Subotic, if he doesn't sign a new contract. Though, Subotic is younger about three years than Cahill, and it does seem that the serbian is better (or at least have a better potential) than the englishman. That being said, all depends where Chalobah and Kalas are in our plans. If the board rates them highly and reckons them to have a futur at our club, then Cahill would be a better choice, as he wouldn't last long. But, I'd rather us to buy a right back, and to have Ivanovic as Terry's successor and buy a right back (or promote one from our academy) than to buy any defender.
