Manchester United striker Romelu Lukaku will need to deal with a "massive jump" after switching to Old Trafford from Everton earlier this month, club captain Michael Carrick has said.
The 24-year-old Belgian international made his debut in a 5-2 friendly win over LA Galaxy on Saturday and Carrick, who joined United from Tottenham Hotspur in 2006, expects the striker to thrive in an environment where expectations are high.
