Tranmere 1-0 Forest Green
As half-time approaches, we've only had one shot on target so far.
That was Ollie Banks' super opening goal.
Tranmere 1-0 Forest Green
Tranmere's leading man James Norwood is limping after landing awkwardly on his ankle, but he seems keen to try and run it off.
Tranmere 1-0 Forest Green
Tranmere are full of confidence now and keen to shoot whenever they have the ball on the edge of the area.

In a bid to steady the ship, the 10 men make a change.
Midfielder Junior Mondal comes off and Lee Collins comes on. I think they'll be switching to a back three, with wing backs.
Tranmere 1-0 Forest Green
Image source, Rex FeaturesWow, Tranmere could be almost out of sight, but Norwood fires just off target again.
The man with 29 league goals for the season chests the ball down at the far post from a corner but - to everyone's surprise at Prenton Park - he blasts over from a few yards.
Forest Green rode their luck there.
Tranmere 1-0 Forest Green
Tranmere's top scorer James Norwood almost has a goal against his former side, as he fires in to the side-netting.
Half the crowd thought that was in.
Tranmere 1-0 Forest Green
It's only Ollie Banks' fourth goal of the season, but it's surely his most impressive, and very probably his most important.
Ollie Banks
What a cracking strike to give Tranmere the lead. Ollie Banks is given plenty of room outside the area to steady himself and fire a powerful effort at goal.
It bounces down off the underside of the bar and back out.
But the ball was clearly over the line and the referee John Busby points to his wrist to indicate the goal has been given by the technology, and correctly so.

At the other end, Emmanuel Monthe defends well to hold off Christian Doidge.

Jay Harris takes Tranmere's first notable shot at goal of this game, but he fires straight at Forest Green defender Nathan McGinley from just outside the area.
Some home fans appeal, claiming that hit McGinley's arm, but there's nothing in it.
Tranmere 0-0 Forest Green

Tranmere 0-0 Forest Green
It's such a needless red card, from the visitors' point of view. They'll be really frustrated at that.
Former Dundee United defender Gavin Gunning can have no complaints. He didn't need to react like that.
It's been a physical start to this game, with some rough challenges flying in, and now it's 11 v 10.
Tranmere 0-0 Forest Green
Image source, Rex FeaturesGavin Gunning is shown a straight red for the visitors!
He tumbles over under a slightly clumsy challenge from Jay Harris, but then Gunning kicks out at the Tranmere man while on the ground. It's a no-brainer for the officials.
Gunning's season is over. And Forest Green have a tough task here now, with so long left of this first leg.
Tranmere 0-0 Forest Green
The team finishing fifth has won the play-offs just once in the past nine League Two seasons, with Southend going up in 2014-15.
Is that a bad omen for Forest Green?
Tranmere 0-0 Forest Green
Forest Green are playing some tidy stuff in these early stages, but Tranmere are looking slightly the more eager to make a break in to the penalty area.

Laura: Come on T, externalranmere Rovers. Soft spot for my local team.
Tranmere are one side that have some pretty illustrious neighbours on Merseyside, but I have a feeling that there is no shortage of love for them.
Tranmere 0-0 Forest Green
Forest Green left-back Joseph Mills goes on a brilliant run, carrying the ball about 50 yards down the left flank, but it doesn't come to anything in the end for the away side.
No chances to report just yet.

I'm sure they'd love another one tonight.
Tranmere 0-0 Forest Green
Forest Green Rovers get this game going. Tranmere are in their traditional white shirts and blue shorts, but the visitors are in their changed black strip, with a splash of green.
