The Argentine superstar has the most goals and assists for the Catalan giants this season, a stat replicated by Shaqiri at the bet365 Stadium.
Shaqiri has scored seven times and created six for his team-mates this season, finding the back of the net three times in his last five appearances.
That has not been enough to lift Stoke out of the relegation places, though, and Lambert has called on the rest of his squad to step up and ease the burden.
"I don't think you can be too reliant on one player," he told a media conference.
"I think it is a difficult thing for that to happen unless you are Lionel Messi or that type of player.
"Xherdan Shaqiri has done well for us but he needs a little bit of help as well.

"We need it from other areas on the pitch, if we get that we are certainly in the game. I think that's where if everybody chips in with some goals we stand a better chance."
