The Steelmen defeated 'Gers 6-1 in a two-legged relegation-promotion clash which denied the Ibrox club the chance to move back into Scotland's top flight where they would resume Old Firm hostilities with arch rivals Celtic.
Ex-Well and Hoops star Lambert knows the result does not suit his home city but acknowledges that Ian Baraclough's side thoroughly deserved to retain their top flight status.
"It's maybe not good for Glasgow or Scotland because the city needs a strong Rangers, as well. But you earn the right and that's why I think Motherwell deserve to stay in the league. They were the better team over those two legs.
"If I was a Celtic player, you would want your strongest rivals to be in the league because you need that."
