Rom was further ahead physically than Gerry. Gerry has had 2 seasons here and a season at Milan and still is always knackered after 60 minutes.
Don't get me wrong he has the potential to be a great player, very skillful, I love watching him play, but he will never be the high energy, high tempo, aggressive player Koeman wants. Best he goes and best of luck to him, I really enjoyed having a player of his skill on the pitch at Goodison.
