Sir Alex Ferguson claims he is "sure" Wayne Rooney will end his career as Manchester United's greatest ever goalscorer.
The 26-year-old is already the sixth-highest goalscorer in the club's history and has the opportunity to eclipse another record against former side Everton on Sunday.
The England forward has 178 goals in all competitions for the Red Devils - just one goal behind United legends Dennis Viollet and George Best, who are tied for fourth.
Next on the list are Jack Rowley (211) and Denis Law (237) with Sir Bobby Charlton's tally of 249 goals the target to beat to become the all-time leading scorer in United's illustrious history.
With Rooney having scored 31 goals already this season, he could require fewer than three seasons to claim the crown and United boss Ferguson believes it is just a matter of time before the player re-writes the record books.
"He's got time on his side to beat all types of records now," said Ferguson.
"What did Bobby get? 249? He's every chance of beating that, hasn't he? He's on track to do that, I'm sure he will do it.
"It's a fantastic record (to move fourth). It will happen of course, hopefully it happens Sunday. But it will eventually happen and it's a marvellous achievement, We've had a clutch of players who've scored an incredible amount of goals at the club, from Bobby Charlton down.
"Wayne is the one player who has scored regularly for us this season. I always felt a few years back that Wayne was a player who got goals in clutches, now it evens itself out which is good. He got two for us last Sunday and his goalscoring record is terrific."
Rooney will be part of the United team that can extend their lead to eight points at the top of the Premier League with victory against the Toffees.
And Ferguson is confident his star performer will once again deliver when the stakes are highest.
He added: "At the end of the day, it's an important game Sunday and I always said of Rooney, he's a player who plays on the edge, he likes the edge of a big game, put it that way, and it's a big game Sunday."
