Crystal Palace manager Frank de Boer has admitted that the club will need to bring in a few more fresh faces if they intend to be a 'solid' Premier League side.
The Eagles boss has brought in Ruben Loftus-Cheek on a season-long loan from Chelsea, while a move for Ajax's Jairo Riedewals is also close to completion.
However, De Boer believes more signings will need to be made in the coming weeks if Palace want to be competitive over the entire season.
"The Premier League is a very tough league and if you want to be a very solid club you can't count on only 12 or 13 first-team players, but normally 16 or 17," he said, according to Sky Sports.
"If we want to be a solid club we need some extra players."
On the Riedewald deal, he added: "It's not 100 percent done so we have to wait [for Riedewald]. Hopefully, it is going to be a very short time."
