A first-half wonder goal from Jed Wallace set Millwall on their way to a third straight home win, which extended their unbeaten Championship run to 15 games.

Lee Gregory produced a fine back-heel for strike partner Steve Morison who doubled the Lions’ lead early in the second-half to seal the three points.

Here are five things we learned...

Jed Wallace’s registers his own Goal of the Season contender

The 24-year-old has been one of Millwall’s best players this season and on his day, has shown glimpses of a player that could one day grace the Premier League.

His early strike against Bristol City was by far his best goal of the season and won’t have scored many better in his career.

Wallace picked the ball up on the left and drove forward before curling the most audacious strike into the top-right-hand corner, with Robins goalkeeper Frank Fielding beaten.

The play-off race is heating up

Despite Millwall’s main two top-six rivals, Middlesbrough and Derby both winning comfortably, the Lions moved up to seventh and remain just a point outside the play-offs.

Another crucial week lies ahead for Neil Harris’ side as they travel to Bolton on Tuesday before playing Sheffield United at Bramall Lane on Saturday. 

Boro have tough fixtures of their own, as they face Chris Wilder’s Blades in midweek, before hosting Bristol City just four days later.

Lee Gregory produces a moment right out of the top draw

When Morison swept home to double Millwall’s lead, the Lions captain was mobbed by his teammates, and rightly so, after producing a fine finish to make it 2-0.

But the provider for the skipper’s fourth goal of season was Gregory. He played the most extraordinary back-heel into his path and Harris was keen to praise his number nine. 

He said: “If Gregory's back-heel for the second was in the Premier League, it would be shown time and time again.”

Harris chose the same starting XI again

The Millwall boss named an unchanged side for the fifth successive game. Tom Elliott’s start at Hull City last month has been the only change Harris has made in the last ten games.

The Lions have won eight times in that period and conceded just five goals in the process, so it’s easy to see why Harris is sticking with the winning formula.

Another full house at the Den

Millwall’s home attendances have improved since their play-off push has gathered pace and another massive crowd turned out to see them defeat Bristol City.

The official attendance was 16,081, the Lions’ third highest of the season. 

It’s not hard to see why so many more supporters have turned up in recent weeks as the South Londoners swept aside their top-six rivals.
