Rio Ferdinand is backing new Tottenham boss Thomas Frank to make an immediate impact at the club next season.Frank left Brentford to succeed Ange Postecoglou as Tottenham manager last month and is relishing the task of steering the club through next season’s Premier League and Champions League campaign.GettyThomas Frank faces a true test of his managerial capabilities next season[/caption]The 51-year-old spent seven years in charge of Brentford and helped establish the west London club as a top-flight club.Frank was rewarded with the biggest role of his managerial career in taking over at the Tottenham Hotspur Stadium but despite his previous heroics, it remains to be seen whether he can improve the club’s fortunes.Spurs may have ended their 17-year trophy drought with victory in the Europa League but their dismal league form was the catalyst for Postecoglou’s sacking.A repeat of last season’s 17th-place Premier League finish thanks in part to a whopping 22 defeats will not be accepted and Frank will hope to see an immediate improvement to his side’s domestic form.Former Manchester United defender Ferdinand says he hopes Frank is successful in his new role, especially after speaking to the man himself.“I really want them (Tottenham) to do well because I’ve been lucky enough to share a couple of dinners with Thomas Frank and he was super impressive, albeit at Brentford,” Ferdinand told talkSPORT. “No disrespect, but the expectations are very different at that football club.“He seemed like a very calm, assured, confident guy. I’ll be very surprised if he doesn’t adapt to his new surroundings and remain successful there.Asked what success might look like for Frank and Spurs next season, Ferdinand replied: “I don’t know? They’ve got no big egos and superstars at the football club that he has to deal with, that would have been the only concern.“I think there’s a group of players whose ears are open and they want to learn and be consistent. I’ll be surprised if he doesn’t deliver that at least.”Frank is slowly tweaking his new squad ahead of next month’s big kick off.Rio Ferdinand believes Thomas Frank will help Tottenham find some consistency in their domestic formRex FeaturesTottenham have completed the signing of 20-year-old defender Kota Takai from Kawasaki Frontale – Frank’s second signing since his arrival.The Japan international joins Mathys Tel on the list of summer recruits following his £30million switch from Bayern Munich after spending the second half of last season on loan at the club.Kevin Danso also makes his loan spell permanent from RC Lens, while young defender Luka Vuskovic completes a switch from Dinamo Zagreb.Spurs are looking to further bolster their squad particularly in attack.They have shown interest in Crystal Palace’s Eberechi Eze but currently appear closer to landing West Ham United’s Mohammed Kudus.They have bid £50million with add-ons but have been told to improve that offer to a guaranteed £60m.Tel has completed a permanent move to TottenhamGettyGettyRicharlison could be on his way out of the club this summer[/caption]That’s because their last offer included clauses surrounding winning the Premier League and Champions League.Brentford forward Bryan Mbeumo has also been linked but appears closer to joining Manchester United.That could see Brazilian forward Richarlison end his stay at the club this summer.Reports claim Frank has already informed the 28-year-old that he will not be in his plan next season and to begin looking for a new club.Brazilian club Vasco da Gama are believed to be interested in the star, however his £175,000-a-week wages could prove to be a huge stumbling block.Vasco are interested in a permanent deal but Richarlison will need to lower his wage demands if the Brazilian outfit hold any hope of pulling off the move.Richarlison could join former Liverpool and Aston Villa ace Philippe Coutinho who secured a switch to Vasco last week.
