(Reuters) - Tottenham Hotspur manager Nuno Espirito Santo was impressed with his team's strong first-half performance in Sunday's 3-0 Premier League home defeat by Chelsea but conceded that they have many problems to solve.

Tottenham put up an energetic display in the opening half of Sunday's game but they had no answer when Chelsea roared back after the break with goals from Thiago Silva, N'Golo Kante and Antonio Rudiger to go joint top of the table.
