Marty Quinn admits that his Glenavon team are badly in need of a win as they head into Tuesday's Carling Premiership clash against Cliftonville at Solitude.
The Lurgan Blues have lost three of their opening four games and have yet to record a win.
"The pressure mounts and the pressure mounts within myself," said Quinn.
"It's massive but I will do what I think is best for Glenavon and if things don't turn around, the situation will have to be looked at."
Former Cliftonville and Coleraine boss Quinn was active in the transfer market during the close-season with highly-rated Kevin Kelbie and Peter McCann among the arrivals but the new players have yet to make a positive impact.
The Glenavon boss says his team had plenty of possession in Friday's 1-0 derby defeat by Portadown but "lacked a bit of creativity" in attack.
"We lacked the killer ball and we lacked people to take a potshot when we were in and around the 18-yard box.
"It's of concern that we aren't scoring goals and certain players aren't living up to the standard that they could be."
Linfield headed the table on goal difference after the weekend fixtures but manager David Jeffrey was far from happy with his team's display in the 1-0 home defeat by Glentoran.
Jeffrey felt his team were still unlucky to lose against the Glens but accepted that "too many players didn't perform to their potential".
"We have to put matters right and get back on track starting (against Lisburn Distillery) at Ballyskeagh on Tuesday."
Glentoran boss Scott Young was thrilled with the players' efforts in the win over the Blues but he is cautioning against any complacency going into the game against Coleraine at the Oval.
"Tuesday night will be a difficult game. They always are against Coleraine," added Young.
"I know Oran (Kearney) because we did the pro-licence together and I know he will have his team well-drilled."
After David Scullion's last-gasp goal earned Coleraine a draw at Seaview on Friday night, Kearney was back in Belfast to watch the Glens win Saturday's Big Two clash.
Portadown go into their home game against Dungannon Swifts level on points with Linfield and Glentoran.
Dungannon moved off the bottom of the table on Friday night by beating Carrick Rangers 3-1 at Stangmore Park.
In Tuesday's other game, Ballymena United host Carrick Rangers at the Showgrounds.
