Manchester United boss Ole Gunnar Solskjaer has called on the club to spend money on new signings before this summer's transfer window closes for business.

The Red Devils suffered a 3-1 defeat to Crystal Palace in their Premier League opener on Saturday night, and it was a laboured performance from the 20-time English champions.

Donny van de Beek came off the bench to score in the latter stages, but the Netherlands international is the only new signing at Old Trafford this summer.

The club's executive vice-chairman Ed Woodward has suggested that United will be unable to make any big-money signings before the end of the transfer window due to the financial impact of the coronavirus outbreak.

However, Solskjaer has insisted that the club must improve the squad before the October 5 deadline.

"It has hammered home that we need to improve. That is not good enough against any team in the Premier League," BBC Sport quotes the Norwegian as saying after the clash with Palace.

The Red Devils continue to be linked with Jadon Sancho, but Borussia Dortmund could allegedly demand more than £110m for the England international in the final stages of the transfer window.
