Cullen has been on loan at Charlton from West Ham since 2018 and has established himself as an important player for the Addicks.
As reported by London News Online, the 24-year-old is under contract at Premier League club West Ham until the summer of 2021 after the London outfit activated a clause in his contract.
Charlton manager Bowyer, who played for the Hammers in the 2000s, believes that Cullen will have offers from clubs.
Bowyer told London News Online about Cullen: “If West Ham went down then I think he’d go back and play there.
“If they don’t go down then I don’t know what will happen. I’ll be surprised if someone doesn’t try to buy him – he’s a manager’s dream.
“Josh is just a machine. He is everywhere. He breaks so much up and doesn’t give the ball away.”
West Ham United future?
Cullen is a very talented and promising midfielder, but he is 24 years of age at the moment and is not in the ‘young’ category any longer.
The Republic of Ireland international midfielder has made only a handful of appearances for the West Ham first team so far in his career, and one should not be surprised if he leaves the Premier League club on a permanent basis in the summer transfer window.
According to WhoScored, Cullen has scored one goal and provided two assists in 29 Championship matches for Charlton so far this season.
