Coventry City manager Andy Thorn has urged City supporters to get up the Ricoh Arena for the remaining two games and back the team.
Speaking to Sky Blue Player, Thorn said: "The support we have got this season from our home and away fans has been phenomenal. We can't ask for anymore and they love their club.
"That support has kept everybody going here and without that support, the situation would be a lot different. We do need more of the same though going into these last two home games.
"We want to do well for them and make sure we represent them very well on the pitch. We want to repay their faith in us and the support that they have shown us.
"Make sure you do come to the game because we want a good atmosphere and with that there, it is always a real boost for us.
"It keeps the boys going and it has been absolutely fantastic this season and we are desperate to repay them with some victories to make sure we keep this club up."
Millwall have sold 577 tickets for the game.
