Inter Milan coach Luciano Spalletti says Gabriel Barbosa needs to prove himself in preseason.
Spalletti was asked about the Brazilian's situation.
He said, “Gabigol? Gabigol paid attention to what I asked of him, I know him well enough.
“There are games he's played that I could go and see, but then training also counts, even friendlies.
“It's the footballer who has to give the answers though, just like all the others."
