CLUB captain Paul Robinson insists he is ready to handle the physical demands of Championship football.
Robinson has not played a league game for the Lions since September 2012 but is fully fit again after battling back from a string of injuries.
And the 31-year-old, who has been on the bench for Millwall's three games so far, is now hoping to make his first start of the season against Sheffield Wednesday on Saturday.
"You have got to respect the fact that Mark Beevers and Danny Shittu both had excellent seasons last year," said the centre-back.
"But I've not missed a training session and my body feels better than I expected it to. I feel I have a lot of offer, not just in terms of how I play but also my leadership qualities.
"Dave Jones always has Wednesday well organised. They're a big, strong team and it will be a tough game."
Robinson sees no reason to panic despite Millwall's losing start to the campaign and believes it is only a matter of time before results pick up.
"We are disappointed with the goals we've conceded from set pieces," he said. "They were sloppy goals, especially against Ipswich.
"There is very little between the teams at this level, the games are very tight so it is important we stay mentally strong and focused. We need to be the team scoring the goal from a set piece rather than giving it away.
"Against Huddersfield we were much the better team in the first half but unfortunately for us we didn't score when we were on top. It seems like when we don't get it right at one end, we get it wrong at the other and that's cost us.
"They are little details but you need to get those right to get the edge in games; we're playing quite good football and we are not far away.
"The manager's energy is infectious and the mood is still very positive."
