Andy Awford has called for the club to unite as Pompey strive to bounce back against Morecambe.
The Shrimps visit Fratton Park tomorrow eager to bolster a League Two play-off challenge which currently puts them in eighth place in the table.
For the hosts, who trail three points behind Jim Bentley’s side, the fixture takes on massive significance – particularly for an under-pressure Awford.
A dreadful week, capped by FA Cup elimination at the hands of non-league Aldershot, has escalated the fan criticism in the manager’s direction.
Yet Awford remains defiant, determined to turn around the Blues’ current poor form.
And he has urged supporters at Fratton Park to once again get behind the team tomorrow in their attempts at picking up a crucial victory.
‘What I will say is I won’t desert our players,’ said Awford.
‘We have got to do better as a group and the only way we will do that is by sticking it out, seeing it through.
‘We ask the supporters for everything at our football club and I’ll ask the supporters again to show some support tomorrow – as hard as it may be.
‘At the end of the game, if they need to boo then boo. I have never had a problem with that, but during the game I need the supporters to stick with us, I really do, and I know they will.
‘The fans are the football club and they will come in their droves again and will support us, the players know that and I know that.
‘But we cannot keep letting them down, it’s not fair.’
Morecambe have won four and lost four of their eight league away matches.
