The 19-year-old will sign a 5-year deal with the Eredivisie giants upon the completion of his medical on Monday, with the fee believed to be in the region of 8 million euros.
The Eindhoven side were in the market for a new attacking midfielder due to the expected departure of Ola Toivonen this summer and identified Maher as the ideal candidate to replace him.
“It had been our wish to lure him to PSV for quite some time. I am very pleased with his arrival, because we really wanted him,” sporting director Marcel Brands commented to the transfer.
“We have signed yet another talented Dutchman, which suits our philosophy.”
Arsenal and Manchester United were two teams interested in the talented midfielder but were to slow to make a move.
Maher becomes PSV’s third signing of the summer after the previous arrival of Jeffrey Bruma and Florian Jozefzoon.
