Roberto De Zerbi may have just thrown a big hint regarding Dejan Kulusevski, as the Tottenham star continues working towards full fitness.There is now genuine optimism at Spurs about Kulusevski as the attacking midfielder enters the final stage of his rehabilitation after more than 500 days out of action.The extended international break has given the attacking midfielder some crucial extra time to work towards full fitness, with some reports suggesting that Kulusevski could be ready to play in one of Tottenham’s next few fixtures.According to reports, the 26-year-old’s progress has lifted the morale of his Spurs teammates, as the Lilywhites attempt to get their season up and running after a poor start.Credit: @thefrederikkejensen / InstagramTottenham may have hinted at Dejan Kulusevski’s role under Roberto De ZerbiWhile the Swede did feature as a number 10 on several occasions under Ange Postecoglou, he has overwhelmingly operated as a right-winger since his move to Tottenham.After watching the latest training video released by Spurs, Alasdair Gold pointed out that Kulusevski was training to play centrally rather than out wide.Gold wrote in Football.London: “The 26-year-old looked bright in the training footage from this week and set up teammate Mohammed Kudus for a couple of goals with some incisive passing. Despite the Ghanaian having been at Spurs for more than a year now and suffering from his own long-term injury, the two attackers have never played in a game together.“With Kudus operating down the right and Kulusevski feeding him the ball into his runs in the small-sided mini-games, could Kulusevski be the number 10 De Zerbi turns to when he’s fully fit, with Maddison and eventually Xavi, rather than his more regular role as a right winger before his injury?”Gold impressed by Spurs defender’s key attributeThe Football.London journalist was also struck by what he saw and heard from one of Tottenham’s deadline day signings in the training footage.Gold pointed out that Tosin Adarabioyo’s voice could be heard throughout the four-minute video, suggesting that the Englishman is the sort of vocal presence that Spurs have lacked in their backline.Gold added: “There was one noticeable player voice constantly heard during the training sessions, and that was summer signing Tosin Adarabioyo.“In the training footage shown this week, Adarabioyo was constantly talking to those around him and barking instructions at his teammates, young and old. Spurs need some strong voices and personalities in the squad, and they could need the former Chelsea and Fulham defender in the weeks ahead as Jan Paul van Hecke has suffered a toe injury.”READ MORE: Arthur Dias transfer update: Tottenham watch on as centre-back makes Brazil debutThe post Tottenham expert spots something interesting about Kulusevski and Tosin in training clips appeared first on Spurs Web.
