Crystal Palace coach Frank de Boer insists he will continue to look for more signings as he tries to add “quality” before the transfer window closes.

The Eagles, 2.75 to be relegated, have already added Jairo Riedewald, Ruben Loftus-Cheek and Timothy Fosu-Mensah to their squad for the upcoming campaign.

However, they have been unable to help Palace so far and De Boer’s men have lost all three Premier League games to Huddersfield Town, Liverpool and Swansea City.

Palace chairman Steve Parish claimed over the weekend that Palace still have some firepower left in the transfer market and De Boer admits they need more quality.

He told Sky Sports: “We are looking for players of course. But it has to really give quality to us. We will see.

“The club is focusing on the players that maybe we are going to get, and I am focusing on the team to get the right freshness for the Burnley game.”

Palace continue to be linked with Liverpool centre-back Mamadou Sakho, who enjoyed a successful loan spell at the club last season.

However, he is valued at £30million by the Reds and De Boer insists he does not know if the club could bring in the Frenchman.

He added: “I don’t know. We know what kind of impact he had last season. But for now, I can’t say about it.”

Palace’s next league game comes after the international break and De Boer will be hoping he has strengthened his squad for the trip to Burnley on September 10.
