Manchester City boss Mark Hughes is planning a January bid for Barcelona striker Thierry.
The Daily Mail says former Arsenal striker Henry is expected to leave the Nou Camp after failing to make an impact in Spain and Manchester City boss Hughes has asked to be kept informed of developments.
City desperately need a reliable forward to complement their attacking midfielders because Hughes and his staff feel Brazilian Jo, 20, will not come into his own for another year at least.
Henry, 31, has been at Barcelona for a little over a season but has never settled and is keen to return to England.
