Toadie Kits should be alright in the Prem, but probably won't score more than 15, just because of the step up in quality of the defenders.
My main concerns about players in the Prem are Blakey and Murts, both technically alright, but not the quickest I've ever seen, and pace gets more and more important the further up the leagues you go!
If he was to get anywhere near 15 goals, I would be delighted. I too have my reservations about Kitson in the Premiership. He's been outstanding for us since he joined, but I just worry that he doesn't have technical ability for the step up.
