Roy Keane said in an interview with his "Sky Sports" that Manchester United's current situation is worrying, and that Solskjaer's honeymoon period has ended and a transfer must be made this week.
Keane said: "So Shuai's honeymoon period is over, he needs to win a trophy this season."
"Especially last week's performance, now his pressure will start to increase."
"The performance against Crystal Palace was not as expected. Everyone knows how bad their defense is."
"If they don't carry out a transfer operation next week, then the following days will be very difficult for Manchester United."
