Manchester United legend Ryan Giggs expects Romelu Lukaku to start at Brighton.
Lukaku began last week's victory over Leicester City on the bench.
Giggs told Sky Sports: "I would imagine Romelu Lukaku, if he is fit, will come back into the line-up at Brighton as he's obviously Jose Mourinho's first choice, but United do have options in Marcus Rashford and Alexis Sanchez as well if he's not ready.
“I think he's proven over the last five or six years to regularly get around the 20-goal mark so he's the main man for the centre-forward role; it's up to the others to step up and provide competition."
