Why Portsmouth fans will be hungrier than ever when football does eventually return

But the striker believes Blues fans will be more vociferous than ever if they are allowed into grounds when the season recommences.

The coronavirus outbreak has suspended English football until April 30, although it’s expected that date will be pushed back further as the pandemic worsens.

What's more, there's still uncertainty whether supporters will be able to attend when games do eventually get under way.

The backing from the terraces has been a key factor behind Kenny Jackett’s side's League One promotion push.

Pompey are the only side in the division who remain unbeaten at home – winning 12 and drawing six of their 18 games.

The ‘hostile’ atmosphere away teams meet is why Harrison believes Fortress Fratton is such an asset to the Blues.

And when followers of Jackett’s men do return in their droves, they’ll be even more fervent.

The former Ipswich forward said: ‘It will be a big lost if I’m being totally honest (if games were behind closed doors).

‘It’s not because we’re the best team in the world – we're not a Liverpool who's going to smash teams even if they played on a 3G pitch on a Sunday.

‘We are Pompey and we are still beatable. But when you have got 18,000 fans behind you, for the other team it is hostile.

‘When the fans are behind you, no other team would want to come here and get abuse. I wouldn’t want it and I didn't want it when I came with Bristol Rovers a few years ago.

‘It doesn’t make you feel good because you're playing against 12 men.

‘It would be a miss, a huge miss. The fans will miss it, but if they carry on the season as normal then the fans will be even hungrier to come back and shout because they haven't been able to do so for a weeks.

‘Hopefully, the plan can be to come back and be as it was but who knows. We've still got to win if there is one fan or 50,000 fans in the stadium.’

While Harrison and his team-mates are undergoing their own fitness programmes at home, he insists no focus has been lost in the bid to achieve promotion to the Championship.

He added: ‘There are 10 games left and when the season does restart, we’ve got to go out there and get promoted.

‘Nothing has stopped in terms of that. We still want to be promoted and still want to get to Wembley and win the cup.

‘It’s just when it happen because now we're just waiting to do it.’
