It may have ended in defeat, but Igor Tudor’s first game as Tottenham manager revealed a lot to us when it comes to what to expect for the rest of the season.Sadly, Tudor was unable to make an impact this weekend, with Spurs ending up on the wrong end of a 4-1 defeat to local rivals Arsenal.Tudor has been backed to save Tottenham from relegation still, but we’ll need to see far more from the players in the coming weeks if that is to happen.Regardless of the result, here’s hoping those players learned a valuable lesson about their new manager and his expectations. We certainly did, so here’s what we noticed about Igor Tudor’s setup based on the North London Derby.READ MORE: Tottenham receive double injury boost as Igor Tudor hints at two returning starsCredit: @thefrederikkejensen / InstagramWhat we know about Igor Tudor’s Tottenham nowTudor played the Tottenham formation we all expectedLast week, Tudor said his style and system weren’t important at Spurs, given their current predicament. But he didn’t stray too far from the playbook in his opening game. We all knew he preferred the 3-4-2-1 formation, and he stuck with it on Sunday.However, it will be interesting to see whether he switches that up to a 3-4-1-2 in the near future. With Richarlison and Dominic Solanke both fit now, Tudor has options in the striker department, whereas other areas of the pitch are depleted due to injuries.He needs Tottenham defenders to push up higherOne of the more concerning images from the weekend was Micky van de Ven seemingly ignoring Tudor’s instructions to push higher up the field. The Croatian was screaming at his captain to advance the defensive line, and while the Dutchman didn’t do as he was told, that does still tell us a lot.We know Tudor likes an aggressive, high-press style of play and the fact that he’s demanding this of van de Ven and co. suggests that it will definitely be a trademark of his reign at Spurs.Guglielmo Vicario was told to play the long ballIn the past, we’ve seen Ange Postecoglou and Thomas Frank clearly instruct their players to play out from the back and to build up play from the goalkeeper. That approach went out of the window under Tudor on Sunday.Guglielmo Vicario played plenty of long balls up to Randal Kolo Muani and Pape Sarr. The only problem is that out of 23 attempted long balls, only two (9%) of them found their target. Either Vicario needs to improve those numbers, or Tudor needs to rethink his methods.READ MORE: Supercomputer changes Tottenham’s predicted Premier League finish after Arsenal defeatTudor trusts the three at the backIt says a lot that Tudor not only started the game with three at the back, but he finished it with the same shape, too. We assumed that, when Mathys Tel was warming up, we would see Spurs go for a more attacking system, but the young winger was employed at wing-back instead of playing higher up the pitch.Even when chasing the game, it would appear Tudor is not going to stray too far from his standard approach. Sounds like a few players may have to get used to playing slightly unorthodox roles from now until the end of the season.Off the ball is just as important as on the ball for TottenhamTudor said a lot about Tottenham’s mentality and the confidence of the players in the wake of the defeat to Arsenal. He specifically claimed he did not see enough from his players off the ball, which means there needs to be a lot more work done.Obviously, Tudor will want his players to perform when they’re in possession, and that’s something he can directly improve on the training ground. However, the work rate and desire to keep chasing the ball and pressing in the right areas is more of a mental aspect, and that’s far harder to make progress on.Only time will tell if Tudor and his Tottenham players can solve the issue and pick up the necessary points to avoid relegation now.The post Five things we learned about Igor Tudor's formation and style in Tottenham vs Arsenal - opinion appeared first on Spurs Web.
