The reliable Hammers news source claims that the Addicks are keen on bringing the 23-year-old back to The Valley, where he spent last season on loan.
Their manager Lee Bowyer is thought to be a big fan of the youngster, who was a regular contributor as Charlton secured promotion back to the Championship last term.
It is beginning to look like Cullen is only on the fringes of Manuel Pellegrini’s squad at the London Stadium, although there are doubts over whether the Addicks could afford to pay more than £1million for him.
It does seem as if Cullen will not be a first team squad member with the Hammers next campaign. He has not played a huge role in pre season thus far, and competition for places in the starting line up will be fierce next time out. Pellegrini has Declan Rice, Mark Noble, Jack Wilshere, Carlos Sanchez, Pedro Obiang and Conor Coventry competing for a starting spot in the centre of midfield, while he will be hoping to fit plenty of attacking midfielders in his team, as well. That likely means that only two of the above group will start each week, which doesn’t leave much room for Cullen. It would appear, then, that the youngster may well be on the move this summer, and Charlton would appear to be the most likely destination for him. He was fantastic for them last time out, albeit in League One, and Bowyer is clearly a big fan. It would very much appear, at the moment, that Cullen will be an Addicks player by the time the new season starts.
