Rafa Marquez said that MLS was a more attractive league than Liga MX for Mexican players returning from Europe.

"I think that MLS is more attractive than coming to Mexico and that we should be a little worried about that. We should try to enamor our players more so that they can come back and that would help the quality of football get better," Marquez told Fox Sports.

Marquez, who previously played for the New York Red Bull, added that the quality of MLS continues to improve.

"I think so," Marquez said. "We saw what happened to Leon, who was beaten by Carlos Vela's [LAFC] and is on an upwards path, and it won't be long before they overtake us."
