British Transport Police are deploying extra patrols at Wolverhampton station and on trains to and from Manchester in anticipation of Manchester United arriving at Molineux on Saturday.
Solskjaer has not completely ruled out the possibility of Romelu Lukaku playing at Wolves although it's understood the Belgium striker is unlikely to feature due to a foot injury.
They could be in for another frustrating 90 minutes against Nuno Espirito Santo's men, who put in an extremely conservative performance in holding Chelsea to a 1-1 draw at Stamford Bridge last weekend. "Obviously we've got a decision to make as to who is match fit".
"Mason [Greenwood] has been ill, so he's not trained this week". "He's not been on grass yet".
Solskjaer overlooked a question relating to a recent report that Sanchez could move on and was hardly wholehearted when asked if United would one day see the best of him.
"You can never be 100 percent sure, but Alexis is such a determined lad..."
It would also be the first time they have played at the "new" Wembley in a cup competition since it was rebuilt in 2007.
"We've done well, we've got ourselves in and amongst top four [in the Premier League], we're in the quarter finals of both the FA Cup and Champions League, we've been on a good run", he said. "You're always measured on results but we played a good game against Arsenal".
'It's so unusual, the Arsenal one. Sometimes you can say that was a bad performance, but we won, then you are happy. "Very disappointed in the result, it hurts more than anything, but it's not like we can't look at the performance and say we were s*** because we weren't".
