Jed Wallace says he's primed to make his Sky Bet Championship return after missing three matches through suspension.
The Lions winger has been a reluctant spectator since his controversial sending off against Burton Albion in early November, but admits the 'frustrating' period hasn't been without a silver lining.
"It's been difficult, of course," Wallace told millwallfc.co.uk.
"But I have used the time where i'm not playing to try and look at the game from a different point of view and keep learning.
"The time off has helped me to understand how I can help my own game and help the team when I come back. Now my suspension is over I hope to come back and do it against one of the high-flying teams in this division."
Wallace will be available for selection for Saturday's match against third-placed Sheffield United.
The Blades have been one of the surprise packets of the division since their promotion from League One last season.
"We showed last year in the FA Cup run how difficult we are to beat when our attitude is right and we are playing at The Den," Wallace added. "That will be no different on Saturday."
"It's a huge game for us and we need to get back to being the kind of Millwall team that gets on top of the opposition and creates chances and shows the quality that we have in the squad.
Millwall will hope to return to winning ways and record three points for the first time since the 2-0 victory over Birmingham in late October.
"It's been a bit hustle and bustle for the last six or seven games but maybe a bit more quality in the final third and we will be there or there abouts this weekend.
"I think we have been a bit unlucky. We have perhaps not had a few decisions go our way or had the bounce of the ball, but these things always level themselves out and we have a difficult run of four or five games to show everyone what we are about."
