Jorge Sampaoli says players like Lionel Messi are being abused by being asked to play so much football in such a short space of time, by the schedule.
The Sevilla boss explained: "I think players are being abused, players like Messi or those who travel to South America and are then playing within two days - it's unfair for the best players.
"It's a topic we need to look at, so we can protect them."
