The former Spurs striker has been underwhelmed with the Belgium international's career in England and feels he could have progressed further
Les Ferdinand is disappointed with how Mousa Dembele's career at Tottenham has progressed, having believed he would be the next Spurs player to follow in Gareth Bale's footsteps and join Real Madrid.
Midfielder Dembele arrived from Fulham in 2012 but has seen his career in north London hampered by injuries.
The Belgium international underwent ankle surgery in May but injured it again in an EFL Cup tie with Barnsley in September, keeping him on the sidelines for over a month.
