Wayne Rooney insists that despite him and Javier Hernandez scoring 36 goals between them in their first season at Old Trafford, there is more to come from the pair this term.
In his first season in English football, 'Chicharito' struck 20 goals, including one in each of the four competitions United entered, including in the Community Shield, as he displaced top scorer Dimitar Berbatov from Sir Alex Ferguson's first team.
Once Hernandez had established himself at the top end of the pitch, Rooney began to flourish alongside him, scoring 16 goals last season, 14 of which came during the second half of the season.
Rooney said: "Before he came I'd only seen clips of him, and then I saw him at the World Cup. Then when he turned up, we were excited because you could see what kind of player he is," he says.
"I don't think any of us expected him to do what he did. To come in and cement your place in the team at such a young age is an incredible achievement, and I think he's helped me progress too. I can play in a deeper role and get more of the ball when he's there for defenders to worry about.
"I always want more of the ball and that position helps me see more of it. We suit each other. It could be a partnership for years."
With Edwin Van der Sar, Paul Scholes and Gary Neville having all recently retired, and owen Hargreaves having left on a free transfer, United's squad has something of a youthful look about it, and it could get young still.
A 10th FA Youth Cup win in the club's history delivers further proof that United are building effectively for the future, and Rooney is excited by the proposition of some of those successful youngsters breaking through into the first team.
"The youth team train with the first team at United, we see their progress every day - and Paul Pogba has really impressed me," he says.
"He's gained a few pounds and he was outstanding last season. Then there's Ravel Morrison and Ryan Tunnicliffe... they've all got big futures and hopefully you should see them figure, if not this season then in the next season or so."
