Alan Shearer says Manchester United’s failure to replace Romelu Lukaku means Marcus Rashford and Anthony Martial are under huge pressure to perform this season.
Lukaku completed a £74million move to Inter Milan on deadline day.
The Reds opted against signing another forward.
"
That has put big pressure on Marcus Rashford and Anthony Martial to perform this season - and it's important they avoid any long-term injuries," Shearer wrote in The Sun.
He added: "Martial and Rashford both have to step up. However, in Ole they have a manager who knows their position as well as anyone - and he can pass on all of his experience and expertise. If he can get an extra ten per cent out of them both, that might just be enough - but it is still a gamble."
