The 28-year-old was on loan with the Royals under former manager Alan Pardew towards the end of last season.

"Everything's agreed with Glen, and subject to a medical he will sign a contract on 1 July," said Reading director of football Nick Hammond.

Dean Morgan has verbally agreed a new two-year deal while Louie Soares should sign his first professional contract.

"Dean has accepted our offer and will sign for two further years," Hammond told Reading's official website.

"The deal for Louie is all agreed as well."
