The 21-year-old's loan spell with Leeds United was cut short in January.
And asked by OneFootball.com who he thought was the most promising youngster at the Gunners, Suarez said: "Eddie Nketiah. In fact, I remember talking to Antonio Chaves, Celta's Sporting Director, and telling him that there was a very promising striker coming through at Arsenal.
"He went on loan to Leeds but things didn't work out. And I said if he wanted a striker, he should call him.
"Now he's slowly becoming a regular even if not as a starter, he's having minutes to make an impact.
"It seems like he could be important in the coming years at Arsenal and they should take care of him because he is very talented."
