Barcelona are chasing Lautaro for the summer market, but Capello feels he isn't ready for such a move.
Capello said, "For him, I would stay at Inter. He would be a substitute at Barcelona.
"The market will be revolutionised. Absurd numbers have been reached for the signings. We will return to a more reasonable level.
"Smart managers will be necessary to fix the system. Selfishness can be fatal."
