Rashford returned from a prolific World Cup with a brilliant goal to open the scoring in a move straight out of Carrington. Christian Eriksen drove a low corner into the England international’s path, who latched onto it with aplomb after easily evading the traffic desperately defending the box
Fewer than four minutes later, Martial doubled the lead. Casemiro – who must already be United’s best midfield signing in years – started the searing sweep up-field with a brilliant tackle to rob Forest by his corner flag. The ball found its way to Bruno Fernandes on the counter.
The Portuguese then hit an excellent long pass over to Rashford, who cut inside his defender and teed up Martial to power one through Wayne Hennessey’s grasp.
The home side did survive a VAR check five minutes before half-time when an offside Willy Boly deflected Ryan Yates’ header past David De Gea, denying Forest of only their second away goal this season.
In the final moments, Ten Hag was punching the air in delight when Fred added a third goal, finishing like a striker after fellow Brazilian Casemiro raided forward and threaded the ball through for his team-mate.
