West Ham face Southampton this weekend.
Allardyce told whufc.com: "Lambert and Rodriguez without a doubt, and Lallana if he plays, all three of them have mastered the challenge of the Premier League brilliantly. Their skills and abilities have been shown in abundance. To be honest with you, Lambert has been doing it right from the very start. He has scored goals in every division he has played in now, which is a magnificent achievement.
"Rodriguez, of course, having had time to settle from Burnley, has shown the sort of goalscoring form that he managed at Burnley before. Lallana has always been a good player in my eyes, so that's a very dangerous front three, if those three play. So we'll need to be as good defensively as were against Liverpool."
