Nuno Espirito Santo says Tottenham do not have time to solve their 'many problems' in training and must use matches to improve, as they face Wolves in the Carabao Cup on Wednesday night.
Nuno complained about their lack of wins, levels of performance and absent players, with Lucas Moura and Steven Bergwijn currently doubts for Sunday's north London derby.
Tottenham started the Premier League season well, with three consecutive 1-0 wins, but have since struggled, losing 3-0 in back-to-back league games against Crystal Palace and Chelsea.
'We don't have too much time on the training ground,' Nuno said.
