Man United fans react to Romelu Lukaku's performance against Crystal Palace
Lukaku has netted six goals in his last five matches for United in all competitions and will be looking to add to that tally against the Eagles.
The Belgian worldwide striker has been an inspiration for both club and country so far this season, scoring 14 goals in 11 games for United and Belgium. The Champions League clash in Russian Federation was his 11th game of the season after also appearing in two World Cup qualifiers for Belgium last month.
The Manchester United boss said, "Look, without Zlatan we can not rotate the striker, especially because Marcus Rashford is playing also in other positions".
"So until the moment we have Zlatan we can not think about giving a rest to our number nine, the same way we give in other positions".
"They can always be in finishing areas, in fact I want them to be, so if people like Jesse Lingard, Juan Mata, Henrikh Mkhitaryan and Anthony Martial score goals, I think it's just a natural effect of the way we play". We can not do that. "Belgium is Roberto's (Martinez the national head coach) responsibility and it's his decision to play him or not to play him". "I can not, professionally speaking, say, "Do this or do that".
