As it stands, they could only be a few matches away from the holy grail of English football. 

Another win for Neil Harris' Millwall side has pushed them up to sixth place in the Championship, the final position for the Premier League's promotion play-offs.

Harris has become the Championship's star manager this season, masterminding his side to a possible double-promotion - unheard of in recent English football history.

Millwall currently sit two points ahead of Tony Pulis' Middlesborough side, both having played 42 games.

As it stands, with four games remaining for the Lions, they would face Cardiff City, Mile Jedinak's Aston Villa and Derby County in the playoffs.

Two of their last four league matches matches, however, are against second-placed Fulham and fourth-placed Villa. Another one is against Middlesborough, but to make matters better for the loyal Den fans, Millwall haven't lost a league fixture since January 2. 

From an Australian perspective, it would be the ultimate fairytale for both Socceroos.

Meredith was playing in the Conference Premier only six years ago and Cahill, at the age of 38, stands the possibility of becoming the Premier League's oldest outfield player next season, six years after he left Everton.

Although Cahill is yet to play more than a bit-role for Millwall, both his manager and fellow teammates have been praising the Australia's affect on the dressing room, with Millwall's Jake Cooper crediting him for pushing them towards promotion.

“He’s a great guy to have around the boys and the dressing room. His experience is second-to-none and I think even though he hasn’t had a massive role in the team, he’s helped the team massively, I believe," Cooper told The Independent.

In response, Cahill said he was relishing the move.

"Amazing group of lads and all work for each other," he said. "Pleasure to be a part of this team."
