Demba Ba's agent has confirmed West Ham's interest, but admitted a deal is looking unlikely at the moment.
Hoffenheim have flown to La Manga for a winter training camp, but Ba was not present as they jetted out to Spain amid claims he was heading for England.
However, Hoffenheim spokesman Markus Sieger has confirmed that Senegalese ace Ba will link up with the rest of the squad as planned on Tuesday.
"It is planned that Demba will travel today," he told Deutsche Presseagentur.
Ba's lawyer Ran Ronen confirmed that West Ham have made contact with Hoffenheim.
"On Monday, nothing really new happened," he told Spox. "Today he will fly to La Manga with Ernst Tanner [Hoffenheim general manager].
"It does seem he could move and Demba would like to join a Premier League outfit, this is no secret.
"Joining West Ham? This is something I would put in doubt. I cannot say anything concrete, West Ham did come up with a bid, but at the moment Hoffenheim don't appear to be working on it."
It is believed West Ham would like to take Ba on loan with a view to a £6million deal in the summer.
25-year-old Ba, who spent time with Watford as a youth player, joined Hoffenheim in 2007 and has scored 37 league goals.
