Man United have been largely criticised for their transfer business since the retirement of Sir Alex Ferguson back in 2013.
Speaking on club’s Inside Carrington podcast, director of football Jason Wilcox insists the club have had a shift of mindset.
"You have to bring players in that bring something different to the changing room, but the most important thing is that whenever we’re bringing in a player who comes here, they have to want to improve and they have to be a team player, and understand what it means to be part of a successful team," he said.
"It’s not about putting the Harlem Globetrotters together. If I look at the successful Man United teams, there was very functional players that would die for the badge and there were some mavericks.
"When you talk about (Eric) Cantona, when you hear anybody talk about him, he was an ultimate professional.
“When I look now and I see the car park, the report time is at 9.45am, you see the lads coming in at 8.30am, 8.45am, preparing for training. This is a good sign."
"Last year’s summer window was a lot more chaotic than this one," he admitted.
"This one was really calm. We knew the plan. We knew which players we were going to target. We had our lists. We knew which areas of the pitch we needed to improve.
"Right now I’m having weekly meetings with the recruitment team on the different profiles, the age bracket, the cost, are they attainable… with Ruben as well.
“It’s a real joined-up approach when we sign a player. It’s so many people that are involved in the process. The data team are involved in the process.
“We will then focus all our attention on certain players, and it’s really important that we do the background checks around are they clean-living professionals? This is really important."
