Of course he'll be slow, but he wouldn't have forgotten the technique. Being unfit is one thing, lacking skill is another.
Take it easy cheif. The main reason why kicking skills start to become shyte is because people tend to bulk up. Legs become more heavier, shoulder width much more wider, etc...
I have had the same problem this year, I have bulked up consiberly over the pre-season and i have lost my kicking technique. But dont worry they would get their technique back once they settle in their new body.
Just breathe
