The comments came as Cruyff spoke to Marca about how the two players could fit into the same starting line up.
“It could [create jealousy],” he said. “It’s like with the free-kicks. Neymar takes great free-kicks. And Messi has already shown the same in Barcelona. From now on, who’s going to take them?
“Or the fact that Neymar and Barcelona are with Nike while Leo is with Adidas. These are situations that could cause problems.
“With Neymar on board, I would have planned for the possibility of selling Messi, and some would agree with that, others not.
“You are talking about a team, its players, the things around it…There are too many things at stake.
“That’s why it’s so difficult to manage such a top class squad, there are very few people who are used to doing this.
“If they work out well together then undoubtedly it could be formidable. We will have to wait and see – it could turn out well or badly. It’s a risk. I would not have signed Neymar.”
