Lambert has relished leading the line for his boyhood club.
Sturridge's injury problems have been well documented, suffering from calf and thigh injuries which have kept him on the sidelines since August, and is not expected to return until the new year.
It has been left with Lambert with the responsibility of providing Liverpool's attacking threat, and it is something he is relishing.
He is quoted in the Liverpool Echo, saying: “I am absolutely loving it.
“I am fighting for my place and I am fighting to keep that shirt as long as I can now.”
He has done himself no harm on his last four starts in a Red shirt. He managed to get his first two goals against Crystal Palace and Ludogorets, played a big part in the winner against Stoke City, and caused sufficient problems against Leicester City to help the Reds to back-to-back wins in the Premier League.
Mario Balotelli being sidelined with a groin injury has seemingly allowed Lambert to have a decent run in the side, and seems to have done enough to keep his place as the number one back-up forward in the absence of Daniel Sturridge, and certainly opens up the route of playing two up front together when Balotelli returns to fitness.
The next target for 32-year-old Lambert will be to get his first goal at Anfield for the Reds having scored on the road. This weekend's Premier League game against Sunderland, closely followed by the Champions League decider at Anfield both bring about huge significance for the Reds as they look to build on their latest two results.
