Emanuel Pogatetz has revealed Gordon Strachan is a lot stricter than predecessor Gareth Southgate and, despite their poor form, is still backing the club for promotion.
Middlesbrough have failed to win under Strachan having lost two and drawn one in the three games he has been in charge.
Boro have mustered just one goal in that time, a problem the former Celtic manager has tried to overcome with the loan signings of Marcus Bent and Dave Kitson.
Pogatetz has been a frustrated spectator having made his first appearance of the season against Plymouth last month.
The defender then suffered more bad luck when he suffered a fractured cheekbone against the Pilgrims, although the Austrian is determined to play through the pain by wearing a protective face mask.
"Gareth will be missed but you have to move on in football because that is the nature of the game," he told the Daily Express.
"He was a good manager and he taught me a lot of things, but we now have another manager and he has his own ideas that you hope brings success to the club.
"The new boss is stricter in some ways. Training is very enjoyable but the atmosphere around the club is more strict.
"He believes footballers only have very short careers and they have to do everything they can to get the most out of being professional.
"Our objective is still to go up and we have the players to achieve that. We need to start scoring more goals from all positions and if we do that we will be thereabouts."
Having endured an injury-hit campaign last term the 26-year-old admits that being sidelined this season with a long-term knee injury was tough to take.
"After so long out of the game I just want to get fit and get playing again," he added. "I was injured last season and could do nothing about the club getting relegated.
"That is the hardest thing, because all you want to do is help, but of course when you are injured you are forgotten about.
"I came back and I have to pick up my position in the national team as well as help to get my club back into the Premier League.
"I am not very good at being injured. I don't like it on the sidelines, but I hope all that is behind me now."
