Eric Dier provided Tottenham with a fitness boost by training on Tuesday ahead of the first leg of their Champions League last-16 tie with Borussia Dortmund, while the German side confirmed four first-team stars - including Marco Reus - will miss the clash at Wembley.
England international Dier was absent for Sunday's 3-1 Premier League victory over Leicester City due to a virus but was back involved in Tuesday's session.
However, in the section open to the media, there was no sign of striker Harry Kane and full-back Danny Rose. Despite being initially ruled out until March with ankle ligament damage, Kane was back in training last week.
