Roma tactician Luis Enrique insists there is much more to come from new boy Erik Lamela after his debut strike.
The Argentine scored just seven minutes into his Serie A adventure on Sunday in the 1-0 win over Palermo.
"He's a very special type of player," the Spanish Coach told the Gazzetta dello Sport on Monday.
"He knows how to do some beautiful things on the football pitch. Saying that, though, he has a lot more to learn…"
Lamela, a 19-year-old signed from River Plate in the summer for a fee that could rise to €19m, played in a front-three alongside Pablo Daniel Osvaldo and Marco Borriello.
