Rotherham United remain three points clear at the top of the League One table after a narrow 1-0 win over Lincoln City at Sincil Bank. 

Chances were hard to come by for both teams on the day, but Matt Crooks' goal after 47 minutes proved to be the difference between both sides in this one.

The Millers have now won their last three league games, and will be hoping they can pull clear of the promotion-chasing pack in the third tier at the earliest of opportunities.

Paul Warne's side are next in action on Saturday, when they take on relegation-threatened AFC Wimbledon in a game that they'll be expected to pick up three points from.

But the Millers boss won't be taking them lightly, and will be hoping his side can build on their recent impressive run of form in League One.

We take a look at THREE things we learnt about Rotherham after their narrow win over the Imps on Friday evening.

Rotherham didn't take many of the chances that came their way. 

The Millers have 15 shots in total at Sincil Bank, but only managed to get three of them on target.

Of course, one of them found the back of the net with Matt Crooks' goal proving to be the difference between the two sides on Friday evening.

But Paul Warne will be hoping he can see an improvement in his side's conversion rate in front of goal in the near future, as Rotherham look to win promotion back into the Championship this season.

They're picking up wins, when they're not at their best. 

Rotherham certainly weren't at their best against the Imps, but the fact that they're still picking up three points is something that is definitely a positive.

You have to imagine that they'll sweep teams aside with relative ease when they hit their best form at both ends of the pitch, which they'll know they'll need to do at the earliest of opportunities if they're to retain their spot at the top of the third-tier standings.

The game against AFC Wimbledon on Saturday will be a game where they're likely to have the majority of the ball, and they'll have to take the chances that come their way.

The defensive performance was impressive. 

Lincoln City are a side that are struggling at the moment, but their supporters would have been confident of finding the back of the Rotherham net on the night.

But the Millers defence stood firm, and kept a much-needed clean sheet in this one. They conceded twice against Burton Albion in their last game, and Warne would have been keen to see a much better performance in defence against Lincoln City.

He certainly got that as well as they kept a clean sheet to keep themselves top of the League One table, with just 14 games remaining of their season.
