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.
