Mbappe will officially sign with Real Madrid on July 1 when his PSG contract expires.
But speaking to Sueddeutsche Zeitung, Eberl has accused Real of hoarding talent: “You can always become more greedy with money, but everyone who is greedy with money will gradually become the nail in the coffin of football.
"If at some point all the money leaves (the market), then there will be nothing left to do business with. We are talking about hundreds of millions. It's too much and at some point you have the feeling that it's going to explode.
“At some point it will be oversaturated and Saudi Arabia will come. That doesn't give me good feelings. I have to say that to be fair, but that's the market right now. Money is leaving the market. No club benefits from this.
"The players, the families, the agents, everyone benefits, but not the clubs. In the past, at least the clubs benefited. The money remained in the cycle and that will become less and less.”
