So it's the A477, A40, A48, M4, M3 and M25. That's the route I will be taking to get back in time for Millwall's trip to Wembley.

Having agreed to attend a wedding in Pembrokeshire some months ago, I never imagined then that the Lions would be facing off in this Sunday's League One play-off final – their fourth visit to the national stadium in seven years.

After watching three dreadful seasons end in the inevitable relegation, I genuinely didn't have any expectations going into this one.

But after battling past Bradford City in the semi-final last Friday, Barnsley now stand in the way of an immediate return to the Championship.

Neil Harris, a legend in his own right as a player, now has the chance to etch himself into Millwall folklore as a manager.

When Harris was first appointed as boss to replace the disastrous Ian Holloway, most were just relieved that a proper Millwall character had been brought in to steady a ship that had been sinking at an alarming rate.

He and assistant Dave Livermore had yet to cut their teeth fully in first-team football, so most fans would've been willing to give them time to rebuild a squad bereft of belief or quality.

And after an indifferent start to the season, all signs pointed to a year of consolidation.

Nine months on, consolidation has turned to anticipation as the Lions have roared into promotion contention.

Watching young stars Ben Thompson, Mahlon Romeo and Jordan Archer break into the starting XI alongside seasoned campaigners like Steve Morison and Jimmy Abdou has brought the feel-good factor back to the Den.

This Is Local London:

A once fractured relationship between players and fans has been replaced by harmony.

If we win on Sunday, harmony will be replaced by utter elation.

I'm not usually one for hyperbole, but I believe it would go down as one of the greatest victories in recent Millwall history.

Make no mistake it will be a tough, tough test against a side who defeated third-placed Walsall 6-1 on aggregate.

In Sam Winnall and Adam Hammill they have players capable of causing damage.

At the back Alfie Mawson, once a transfer target for Millwall, has been a stalwart who will relish coming up against Lions captain, Steve Morison.

But Barnsley will be just as fearful of our own attacking threats on Sunday - namely Lee Gregory who will be looking to add to his 27 goals so far.

Gregory and Morison have formed a lethal partnership in front of goal, hitting the net 45 times in total.

This Is Local London:

Centre-back duo Mark Beevers and Byron Webster - impenetrable at times this season - have also chipped in with a few goals at the other end.

As in the semi-final, I find it really difficult to split the two.

Early betting makes Barnsley slight favourites going into the tie, which will suit us down to the ground.

Although the Tykes won both fixtures during the regular season, Sunday will be a test of mettle - a who-blinks-first shootout.

Harris has been there as a player. Let's hope he can go one further as gaffer.

Whatever the outcome, he should be thanked for restoring the supporters' faith in the club.

At last, we've got our Millwall back.
