Manchester United boss Ole Gunnar Solskjaer admits they need to be busy this summer.
Speaking ahead of Sunday's last-day trip to Wolves, Solskjaer said his United side had made significant improvements this season in securing only their second runners-up spot since Sir Alex Ferguson retired in 2013.
However, Solskjaer thinks the club need to be active in the transfer market this summer if they are to close the gap on champions Manchester City.
“I hope we will strengthen with two or three players we definitely need to challenge higher up the table," said Solskjaer. “We are too far behind to think it will come by itself.
"We're not where we aim to be, we've got ambitions to move one place further up but it's been steady improvement. We had a difficult start with a lack of pre-season and lost three of the first seven games.
"That put pressure on the team but they have managed it well and the players have been very good."
