Ian Holloway says his plans to revamp QPR’s squad this summer could be undermined by the shorter transfer window.
Clubs have voted for the window to close on 9 August this year rather than at the end of the month.
Rangers manager Holloway spoke after his side’s defeat at Brentford about needing to create an “identity” for his team.
However, he claims the window closing early could cause problems, suggesting loan signings from Premier League clubs will be difficult to secure, and that it is therefore essential the club get their business done quickly.
Loan signings, including deals with the option of a permanent transfer when the window reopens in January, can still be made up until 31 August.
But Holloway said: “These windows are killing football at the moment, I believe. We’ve got an unbelievably short window in a year of a World Cup.
“So let’s be honest, if you’re going to borrow some of these people on loan you’re not going to get a chance to because all the big clubs will keep them until the World Cup’s over and give their lads a rest, do pre-season and then you’re going to have nothing left.
“We’re right in the middle of trying to sort things out. The work that I want to do to add to this group, we’re going to have to do it lightningly quick if we can.
“What I’m looking at is the boys; where are they and can they help me next year in the Championship?
“Can they help us get our own identity and get us a bit up the league?”
