Ronaldo starred as his side beat Newcastle United in his homecoming last weekend.
He bagged a brace as Man United beat Newcastle 4-1 to fire his team to the top of the Premier League.
Sky Sports' Gary Neville has hailed Ronaldo mania and he's not the only pundit praising the five-time Ballon d'Or winner.
Crouch has also celebrated the return of Ronaldo and even says he may have to switch from Messi to Ronaldo.
Writing in his Daily Mail column, he said: "I have always been a Lionel Messi man. A gift from God. The poise, elegance and everything that goes with his genius is spellbinding.
"But we have reached the stage now where every single record is being broken by the other man in the conversation.
"A change of heart, a switch of sides, could potentially be on its way. Are you even allowed to cross that divide?
"What are the repercussions?"
He continued by highlighting Rio Ferdinand's involvement in Ronaldo's transfer back to Man United and revealed a bet he has with a fan.
"Rio then became one of the individuals lobbying him to make that return to Old Trafford last month," he added.
"When he signed from Juventus, I had a bet with a United fan that Mohamed Salah would score more goals this year. Having watched his 'second debut' against Newcastle, I'm slightly concerned that my wallet might be in danger."
