Liverpool manager Rodgers wants his faltering players to use their disappointing start to the season as a catalyst for a revival in fortunes.
Rodgers is taking the lion's share of the criticism for Liverpool's poor start, with serious questions being asked about his record in the transfer market.
Rodgers said he always believed Liverpool's Champions League fate would come down to the last match at home to FC Basel and he has been proved right.
Ludogorets scored a late equaliser to hold Liverpool to a 2-2 draw on Wednesday that ended the home side's hopes of reaching the knockout stages of the Champions League.
Liverpool goalkeeper Mignolet must take some of the blame for their indifferent start to the season, according to Anfield great Grobbelaar.
A win on Wednesday in Bulgaria against Ludogorets is exactly what Liverpool need to ensure they still have a chance to advance to the second round.
"I can safely say he's the best player I've ever worked with. His mentality, commitment and loyalty he's shown to the football club have been incredible," Rodgers said.
Manager Brendan Rodgers acknowledged his job could be under threat after Liverpool slipped to a third consecutive Premier League defeat at Crystal Palace.
Crystal Palace heaped more misery on Liverpool when they came from behind to win 3-1 in the Premier League on Sunday.
Rodgers's side have looked a shadow of the team that ran Manchester City so close for the title last season and are 11th in the EPL table with 14 points from 11 matches.
Liverpool striker Daniel Sturridge has broken down again with another injury to his left thigh, extending the England international's long spell out of the team.
