In a couple of weeks, when he finds himself 'out injured for a lengthy period'....we can just send him back 🙂
On a more serious note, if Kettlewell can get Watt firing on most of his cylinders again, then he'll be good signing. he's got the skills. If he turns up as Mr Big Baws and doesn't try a leg, then it'll be a waste of time and money. At least, at the end of the day, his loan can be terminated and sent back. Nothing ventured.....
