Roberto De Zerbi has singled out a 23-year-old Tottenham star for praise after his heroics in the club’s 2-1 win over Chelsea in Sydney on Saturday.Spurs had their first big test of the summer against the Blues in front of a capacity crowd, with the game being played with a lot of intensity, as you would expect from a London derby.Despite being reduced to 10 men at the start of the second half after a lapse in concentration from Kevin Danso, De Zerbi’s men showed plenty of fight to keep the scores level, before Richarlison came off the bench to net a stoppage-time winner.The man who was primarily responsible for the win, however, was the one at the other end of the pitch.Credit: acafferyphotographyphotos / InstagramRoberto De Zerbi says Tottenham goalkeeper Antonin Kinsky can improve one aspect of his gameAntonin Kinsky pulled off a couple of outstanding saves in the second half to ensure Chelsea did not go into the lead, including a reflex stop to parry Estevao’s effort onto the post.De Zerbi believes that Kinsky can improve his build-up, asserting that the 23-year-old has all the required qualities to become one of the best in the world in terms of distribution.When asked how good the Czech shot-stopper can become, the Italian told Football.London: “I think he can improve in build-up a lot. A lot. But he will reach, for sure, the top. Working with the goalkeeper coach and me, we (will) create the training just for him to better understand the free player, to understand better everything he needs.“He is very clear with the pass, but he can become faster in the decision in build up. He has all the qualities to become one of the best, also in the build up, the distribution.”De Zerbi reveals why he made Archie Gray captain through the tourArchie Gray wore the captain’s armband for all three of Tottenham’s friendlies during their tour of New Zealand and Australia.The Spurs head coach confessed that the decision was made to give the youngster confidence and to show that he is an important part of the club’s future.When asked why Gray was made captain, De Zerbi said: “Because I am the coach. I decide. (Smiles). No, because I spoke with Ben Davies before speaking with Archie Gray because he is the natural captain. Anyway, I think it has been more important for Archie Gray than Ben Davies. It is like to give Archie something more for confidence. Last season I said he is the future of the club but also the present. He is important for us because he can cover two or three positions on the pitch.“He doesn’t love too much to play right-back. But I think to be a captain you have to think first for the group, team, club and then yourself. It was something more to give him because he deserves to be important for this club, even if he plays in different positions even if not in the first eleven. It’s important. Like Bergvall because for Lucas I have the same opinion, the same idea.”READ MORE: ‘I spoke with another team’ – Sandro Tonali admits ’10-minute chat’ made him choose TottenhamThe post De Zerbi says £12.5m Tottenham star ‘has all qualities to become one of the best’ appeared first on Spurs Web.
