Louis van Gaal insisted Manchester United's defeat to Swansea will not prompt him to panic-buy in the final 48 hours of the transfer window.
United lost 2-1 in Wales to end their unbeaten start to the season but manager Van Gaal, whose defence struggled to cope with Swansea scorers Andre Ayew and Bafetimbi Gomis and whose team have only scored three goals in four league games, said it will not change his thinking.
"It doesn't have any effect," Van Gaal told Sky Sports. "When you are scouting players, you know in advance, more than a month or two months, which players you can buy. It is not in the last moments you can panic."
Van Gaal declined to answer questions about Javier Hernandez, who has been linked with several clubs, and the Real Madrid target David De Gea.
But the Dutchman declared his team were probably "too dominant" at the Liberty Stadium to respond properly when Swansea changed shape in the second half by going to a 4-4-2 diamond system, prompting their comeback after Juan Mata put United ahead.
"The opponent changed their shape," he added. "They started with 4-2-3-1 and at 1-0, they changed their shape and we couldn't cope with that. That is not good. We have lost in that five minutes [when Swansea scored twice] and it was a pity because I think we controlled the game and played very good.
"When you don't know it [the new shape], you have to be compact. You have seen Swansea in the last 20-25 minutes, they were compact and it is always difficult to beat a compact team. We were probably too dominant [to have] the sense to do that."
Van Gaal said he was unworried by United's lack of goals, insisting: "You see the game. We could have scored much more goals. I don't think that is the problem."
He accepted United made mistakes in defence, adding: "When the opponent scores goals, always you can find errors. I have to analyse that with my players."
