Tisdale’s men have won their opening three games of the season overcoming Oldham Athletic, Bury and Charlton Athletic respectively – and after a constructive pre-season, Nicholls states there is a positive vibe within the dressing room.
“Tis has brought in a calmness, he’s made everyone relax and enjoy playing football again – long may it continue.
“The atmosphere has changed 100 per cent - it changed in pre-season, something just clicked. I kept saying it last season, but it has in pre-season. All of a sudden, we were together and were fighting for each other. It was something we were missing last season but we definitely have it now.
“I can't put my finger on it, I can't tell you what it is, but all I know is that it's here now. We're all here fighting, and it's totally different.
The defensive displays of MK Dons this season have earned high praise in the media and from the Dons faithful – something Nicholls has noted himself.
“Whoever has played in front of me has been different class. I think I've only had to make one diving save so far this season, which is a totally different experience from last season, to be honest.
“We have been solid. It is fluid but as a group, we're together and we're such a better team. Joe Walsh is like a new signing since he came back, and Jordan Moore-Taylor has taken it upon himself to be the leader of the defence and to be honest - I'm over the moon with him.
“He's solid, he's a big communicator and he hates conceding goals, like me. I couldn't ask for anything more from the players in front of me. “
