Having finished down in sixth position during the regular season, Grimsby were regarded as outsiders to earn promotion, particularly when considering that none of their following fixtures would be played at Blundell Park.
However, the Mariners have used their underdog status to their advantage, upsetting each of Notts County and Wrexham to book their place in East London.
Both triumphs have come after extra time, Saturday’s contest versus the latter going down in the history books as arguably the greatest-ever game since the creation of the playoffs at this level.
After initially going behind, Grimsby led 2-1 and 4-3 before Wrexham forced extra time, only for Luke Waterfall to power in his second header of an enthralling contest in the 119th minute to secure a 5-4 success.
Even though Paul Hurst has witnessed his team concede four goals in two of their last three outings, the Grimsby boss will have total confidence that his players can outlast Solihull on the biggest stage that their opponents have ever experienced.
That is not to say that the Moors should be regarded as the underdogs for this contest, the West Midlands outfit having recorded six wins in succession.
Unlike their upcoming opponents who have twice played 120 minutes to reach the final, Solihull were afforded a two-week break before their last-four showdown with Chesterfield.
Neal Ardley’s side soon went behind, perhaps owing to that prolonged rest period, but they stormed back to lead at half time and eventually run out 3-1 winners.
Impressively, they have now scored at least three goals in their last five outings, a return which sets up the mouthwatering prospect of a hugely-entertaining clash at the ground of West Ham United.
That said, this is one of the biggest games in the history of both clubs, and shows of character will be just as important as having a cool head in the final third.
