“We’ve got other forward options of course, but Angel and Chongy have been training with us this week so they could be involved,” Solskjaer told the media.
“Chance for anyone who plays, Alexis, Romelu, Chongy or Angel, Anthony and Jesse have done really well for us, they’re vital but then again with Rom and Alexis, they’ve got different skill sets and will be able to show what they can do. So we just need to gel a team together for Monday.
