The youngster made his senior debut towards the backend of last season and has continued to make fantastic progress under Mourinho this year.
He has made 20 appearances in total, notably impressing in wins over Chelsea, Liverpool and Brighton and Hove Albion.
And Herrera, speaking in the club’s match-day programme, noted that McTominay will be important for Mourinho following Michael Carrick‘s departure.
“You saw against Chelsea he was a little more defensive and almost doing the job I did against [Eden] Hazard last season, not exactly the same but similar,” he said.
“He can be more offensive as well and he presses a lot. We know we’re not going to have Michael Carrick after this season so we need to add more midfielders to the team and I think Scott is really ready to play in the Premier League and help the team.”
If McTominay does have the capacity to provide forward impetus, we haven’t really seen it yet. This is not to admonish the young Scot; his influence just seems to come through the miles he clocks on the pitch and his overall discipline in the middle.
The next step, in time, will be to start making people aware of what he can do with the ball at his feet. The arrival of midfield reinforcements in the summer will make that necessary if he is to maintain his place in the first team.
