Gallagher scored his first Premier League goal in victory over Norwich City on Saturday.
Fonte told the Daily Echo: "You can see he's very strong, very tall and very powerful and he has teammates like Jay Rodriguez and Rickie Lambert to teach him so he can only get better," said Fonte, pictured right, who reckons the 18-year-old's strengths are comparable to one of the world's best players.
"He's a little bit like Ibrahimovic. He still has to work a lot to be like him but he has pace, he has power, he's tall so he can be a threat in the air and in behind with his pace. He's a handful!
"He has good attributes for a striker, definitely. If he keeps working very hard he can get to that level and be the full package."
