Portsmouth caretaker boss Paul Hart has called on the board to make a permanent appointment as soon as possible.
The south-coast strugglers have dropped to within a point of the relegation zone after taking just two points from their last nine games.
Hart, the former Nottingham Forest and Barnsley manager, said: "It's a very, very good football club and we're on the fringe of doing an awful lot, so (bringing in a new manager) as soon as possible would be great."
He told Sky Sports News the players had trained well but the departure of Adams, who had less than four months in charge, was still hanging over the club.
Of the training, Hart said: "I certainly enjoyed it and I think the players seemed to.
"They've been very supportive and gone about it the right way, so I'm delighted at the moment.
"It's not a very pleasant time for anybody.
"It happens far too often in my opinion but it does happen and we've just got to get on with things."
