After Alexandre Lacazette had put the visitors ahead, Rafael Benitez's side went in search of a response.
Jonjo Shelvey sent a long, 50-yard ball to Dwight Gayle, who brought it down with ease. The striker had the space and time to lay the ball into the path of DeAndre Yedlin, who fired a low cross into the box, with Perez arriving at the near post to slam it home past Petr Cech.
The goal came in the 29th, in what was a slick and precise team effort to draw level with the visitors heading into half-time.
