"But since the manager's [Clarke] come in, it's been on a different level. He and his coaches have been excellent from day one.
"The thing he worked hardest on was trying to get consistency, in terms of the nucleus of the squad, trying to keep maybe 17, 18 lads together and add to it with quality.
"Keeping the same faces around the squad, that's what you need. It's a lot tighter group, in terms of the whole working environment and the staff.
"He's managed to get us set up in a way I believe suits us with the way we can cause problems to any team and in a short space of time, we have shown that."
