The 21-year-old winger has been a prominent player for the Eagles this season and has caught the eye of some of the biggest clubs in Europe with his performances.
He has laid on ten assists this season in the Premier League and clubs such as Paris Saint-Germain are believed to be interested in him.
Olise is also attracting the interest of big-wigs of the Premier League ahead of the next transfer window.
And it has been claimed that he will be subject to enquiries from Arsenal and Manchester United this summer.
The two Premier League clubs are confirmed for Champions League football next season and have money to spend.
Olise is a player they admire and they will soon probe the possibility of a transfer deal this summer.
Crystal Palace do not want to sell a player who still has more than three years left on his current contract, but they will soon be tested.
It remains to be seen whether the interest from Arsenal and Manchester United leads to concrete offers.
