The England left-back hasn't played since being forced off with a knee injury at Sunderland on January 31.
Manager Mauricio Pochettino told us on the flight to Spain today (Monday 16 October) that Danny is likely to take a place on the bench when we take on Real Madrid on matchday three in the UEFA Champions League.
Fellow left-back Ben Davies hasn't travelled because of illness, but midfielder Mousa Dembele, sidelined of late, is with the squad, as is Dele Alli. The England midfielder is ineligible to play as he serves the last of a three-game European ban following his sending-off against KAA Gent in the Europa League last season.
