The Blackburn boss announced on Thursday that he is to leave Ewood Park at the end of the season, but is still expecting his players to remain professional.
The former Norwich and Aston Villa manager announced on Thursday that he is to leave Ewood Park at the end of the season, having won 10 his 31 games in charge to leave Rovers 18th in the Championship.
The 46-year-old has now been installed as the odds-on favourite with the bookies to take over the reins at Scottish champions Celtic, where he spent seven seasons as a player.
But despite his future being surrounded by plenty of speculation, Lambert insists he will not be treating his team's last two games of the season any differently.
Rovers travel to Rotherham United on Saturday before hosting Reading on May 7th, and the Scot is determined to end his time at the club on a high, adding that he is expecting a high level of professionalism from his players.
He told Rovers PlayerHD: "I've said to the lads to give it everything that you've got in the last two games."
"That is all I ask of you for this club, to give it everything you've got, try and win the next two games, and hopefully that is what will happen.
"Their professionalism will see the games through and we'll go and try and win them. We'll prepare them in the right way.
"We'll do everything we can to win them, it won't change my stance on the way we prepare the team and the way we try to look after them and get them going.
"I'll pick a team that I think will go and try and win, that is the way it always has been. I owe it to the football club to go and try and win."
