Former Everton star Tim Cahill has advised the Toffees to sign big players in the summer in an attempt to keep combative midfielder Idrissa Gueye at the club.
Gueye has been impressive in the English Premier League this season and presently stands as the second-best tackler in the league with 135 successful tackles, behind Nigeria's Wilfred Ndidi .
His outstanding performance in the midfield earned him the Man of the Match accolade as Everton raced to a 2-0 win over Burnley on Friday.
During the January Transfer Window, Gueye was heavily linked with a move to PSG but the Goodison Park outfit turned down a £22 million bid from the French Ligue 1 champions.
With the summer window fast approaching, the Senegal international is attracting interest from league rivals Manchester United as the Red Devils look for a replacement for the departing Ander Herrera.
Cahill believes that Gueye's stay on the Merseyside will be crucial to Everton's success in the future.
"He (Gueye) is a big part of Everton's success," Cahill told SkySports, as reported in the Liverpool Echo.
"He is a brilliant player and every team needs someone like him. It's just the way he goes about the park.
"Of course he is going to be in demand but Everton have to attract big players to keep him at the club. He is going to hopefully be a big sign of what's to come at Everton in the future."
Gueye's Senegal will be participating at the 2019 Africa Cup of Nations in Egypt.
They are placed in Group C against Algeria, Kenya and Tanzania.
