Ben Davies believes that one of Tottenham’s summer signings is going to have a big impact, even though his arrival has not been talked about as much as other big signings.Spurs have signed six players for a combined £237m so far, making this already the highest-spending window in their history.However, the exciting thing for Tottenham fans is that the club are not yet done, with De Zerbi insisting that only 60 per cent of the work has been accomplished so far this window, and adding that more “bombas” are on their way.While big-name additions like Sandro Tonali and Mateus Fernandes have dominated discussions all summer, a senior Tottenham defender has identified the importance of one of the club’s defensive signings.Credit: @oscar.visualss / InstagramBen Davies expects Andy Robertson to make a big impact at TottenhamThe signing of Andy Robertson on a free transfer at the start of the summer was not universally popular among Tottenham fans, some of whom felt that the 32-year-old may be past his best.However, De Zerbi has said he expects the Scot to add character and leadership to the Spurs dressing room, and Davies is also convinced that the former Liverpool man’s arrival is going to be of huge help to the squad.When asked about the arrival of Robertson, the experienced Tottenham defender told Football.London: “He’s come into the team, and he’s a player I’ve played against a lot, but he also brings a lot of experience to the group. It’s early days at the moment, but he’s settled in straight away, and I’m sure he’s going to be a big help for us.”Davies convinced Luca Williams-Barnett has a bright future at SpursSeveral young players impressed for Tottenham in pre-season so far, but the man who has caught the eye the most is Luca Williams-Barnett, who has been described as a “precious diamond” by De Zerbi.Davies has been particularly impressed with the 17-year-old’s fearlessness and confidence, predicting a bright future for the teenager.When asked about the attacking midfielder, the Welshman said: “He’s a really top player. He’s got a lot of potential. I think you can see the qualities that he’s got. I think the next step is developing his habits in the game, but to have a player like him that’s got no fear, that has the confidence to try things in games, doesn’t get affected if he loses the ball. I think he’s got a bright future ahead of him.”READ MORE: James Maddison reveals De Zerbi’s message to Tottenham squad ahead of new seasonThe post Ben Davies says one Tottenham summer signing will be ‘a big help’ to the squad appeared first on Spurs Web.
