Callum Hudson-Odoi admits there's been an instant change in training under new Nottingham Forest manager Ange Postecoglou.
Postecoglou replaced Nuno Espirito Santo at the City Ground on Tuesday and held his first training session on Wednesday.
Hudson-Odoi told talkSPORT: "Yeah that was a session! I can't even lie to you.
"For us, it's building that relationship with him early and getting ideas of what he wants to bring into the team.
"When the manager comes in, you have to make sure that you get that quickly because games happen fast and there's one coming on Saturday (away at Arsenal).
"So for us, it's just making sure we're ready, we're prepared and make sure that everyone just knows what he wants us to do, and hopefully apply it in the game."
