Charlton Athletic are interested in bringing back China international Zheng Zhi.

The 26-year-old enjoyed a successful loan stint with The Addicks towards the end of last season, but returned to Shandong Luneng after the club failed to maintain their Premier League status.

Newcastle United and Birmingham City are believed to be keen on the versatile midfielder, but Charlton have entered the mix and the offer of regular first-team football could be appealing.

According to Zheng's agent Gao Li, the player has welcomed Charlton's interest and is not ruling out a return to his former club.

"Charlton are keen admirers of Zheng's abilities," Li told the Chinese media.

"The club are interested in having him back for another season.

"It is possible for Zheng to return, but the move will require approval from me, the player and the Chinese Football Association."
