The Scotland international has been a big hit at Old Trafford this term under current manager Jose Mourinho.
Indeed, the Portuguese head coach has lavished praise on the 21-year-old for his performances in the middle of the park.
McTominay has even managed to keep Paul Pogba out of the Manchester United team thanks to his performances alongside Nemanja Matic.
The Scottish midfielder has made 18 appearances in all competitions in the current campaign since breaking into the Manchester United team.
McTominay has excelled as a holding midfielder alongside Matic to protect the Manchester United back four.
His performances earned him a first call up to the Scotland squad before he made his debut in a 1-0 loss to Costa Rica in March 2018.
Former Manchester United boss Ferguson spoke in glowing terms about McTominay ahead of the derby clash at The Etihad on Saturday afternoon.
“Scott was a wee bit like David Beckham. When he joined us, he was just a wee small lad and then, all of a sudden, whoosh, he just shot up,” Ferguson is quoted as saying by the Manchester Evening News.
“David didn’t even get into our youth team the year we won the FA Youth Cup until the semi-final.
“It’s a growing thing. Paul Scholes was just a small lad, but he sprouted up to 5ft 8in, the height he is now. Scott was a skelf of a boy, then he sprouted when he became an apprentice.
“In fact, he was playing centre-forward for the youth team. They lost Ashley Fletcher to West Ham and Marcus Rashford wasn’t getting into the team at the time because he was also growing.
So they played McTominay at centre-forward quite a lot, but he obviously developed into a midfield player. It’s possible he grew ten inches in a year.”
Manchester United won the Europa League and the League Cup last season following Mourinho’s appointment as Louis van Gaal’s successor.
The Red Devils finished in sixth place in the Premier League last term but are on course to wrap up second spot in the table.
