Ole Gunnar Solskjaer has admitted that Manchester United will make further signings after securing the services of Daniel James and Aaron Wan-Bissaka.
The Wales international moved to Old Trafford from Championship side Swansea City, while Wan-Bissaka joined the Red Devils from Crystal Palace for a reported £45million, plus an additional £5m in potential bonuses.
United are rumoured to be interested in Harry Maguire, Sean Longstaff and a few others across Europe. However, Solskjaer says he expects more incomings before the transfer window shuts down on August 8.
"Well, it's a long-term and short-term project," Solskjaer told United's official website manutd.com. "You cannot just think three years down the line, and so we've got short-term goals as well, of course.
"I think we've been quite calm and good in the market, as we've got the right people and we're still working on a case or two.
"Of course, we're always looking to improve the squad and, all over the summer I've been in touch with Joel [Glazer, co-chairman] and Ed [Woodward, executive vice-chairman] and all the recruitment and analysis people.
"I've got to say it's been very good so far. I've got the backing and we've got to make sure we don't just jump in and do something rash.
"We've got the people we wanted, for now, and there will probably be some more business being done."
Solskjaer also expressed his delight at the two signings United have already made.
"I know this club, the supporters, staff, coaches and team-mates, we want players who can get us off the edge of our seats," Solskjaer continued.
"Both these players have X-factors, real X-factors, and are great, humble human beings who are hard-working, hungry and just at the start of their careers.
"I'm sure the fans will be delighted when they see their progress. They are here now. Now it's up to them to take the opportunity and prove their worth.
"Of course, we don't expect them to set the world alight on the first day, but they are going to grow into big and very good Manchester United players."
