The Chile international has been getting used to life at Old Trafford in recent days after signing for the Red Devils from Arsenal in the January transfer window.
Sanchez netted his first goal for the Red Devils in their 2-0 victory over Huddersfield Town on Saturday as he looks to establish himself as a regular in the first team at Old Trafford.
The 29-year-old is widely regarded as one of Europe’s top attacking talents and he will be hoping to help fire Manchester United to some major trophies in the coming seasons.
Rooney played alongside Tevez at Old Trafford under Sir Alex Ferguson, and the former Manchester United striker believes that Sanchez possesses a similar style of play to the Argentine.
Speaking on Sky Sports’ Monday Night Football, Rooney said: “Sanchez will do that and they are the players they want, almost like (Carlos) Tevez when he joined Manchester United.
“Those players lift the other players and gets an extra five, 10 per cent out of the players around him. I think Alexis Sanchez will do that.”
Manchester United, who finished in sixth place last term, are currently preparing for their Premier League trip to Newcastle United on Sunday afternoon.
The Red Devils are second in the Premier League table and 13 points behind their bitter local rivals Manchester City in the race for the title this season.
