Manchester United manager Ole Gunnar Solskjaer has admitted it's becoming difficult to sign new players but is optimistic the club can sign one or two more players before the start of next season.
United has so far signed Aaron Wan-Bissaka and Daniel James for a combined fee or around £70 million, and are still in negotiations for more players.
One such player is Leicester's Harry Maguire, who is said to be closing in on a move to United after the two clubs reportedly agreed on a mammoth fee of £80 million.
"I know it's hard getting players in and over the line, we've been doing our jobs. We've been finding, identifying players. Scouting them. But they have got clubs," the manager said ahead of their match against Leeds in Perth, Australia.
"It took time with Aaron, it took time with Dan, but they got it over the line. It's not like we're going to sign 10 players. It can't be a quick fix,"
"As I've said to you, we're working on one or two and we're still hoping but I also understand that the market has changed. Prices have soared."
United have also been linked with Sporting CP midfielder Bruno Fernandes, Newcastle United's Sean Longstaff and Lazio's Sergej Milinkovic-Savic, as they rebuild ahead of the new campaign.
The club finished a dismal sixth in the English Premier League last season, consequently missing out on Champions League football.
