The arrival of Roy Hodgson as the club's new manager has led to speculation that the France Under-21 international may not feature in the long-term plans of the former Fulham boss.
But Ngog enjoyed his best season to date with the Reds in 2009/10 to represent a highlight in a terrible campaign for the club, which ended in the departure of Rafa Benitez.
The ex-Paris Saint-Germain forward featured in 37 matches in all competitions and scored eight goals for a struggling side and, amid the speculation regarding Roberto Di Matteo's Baggies and Sam Allardyce's Rovers, his immediate focus is on improving.
"This season is a big season for me. I need to be consistent, play more and score more," he said. "We have a new manager, who is a great manager, so we have to impress him."
But Ngog has not ruled out a loan move to another club, which could enhance his chances of first-team football rather than competing for a place with Fernando Torres, if the Spaniard stays at Liverpool.
The 21-year-old has been mentioned among the next generation of France internationals under new boss Laurent Blanc following their World Cup capitulation and so regular games at club level will be essential.
With regards to a loan, Ngog said: "I am not aware of it yet, but you never know."
