Tottenham Hotspur have now set their eyes on a 21-year-old midfielder from RB Leipzig this summer following the latest Lucas Bergvall bids.Tottenham Hotspur have lost several of their youngsters this summer transfer window, with the average age of the players sold standing at 21.5 years old, after the sales of Radu Dragusin, Alfie Devine, Alejo Veliz and Luka Vuskovic.Spurs, however, could lose even more young talent this summer, with Lucas Bergvall the latest to attract interest from elsewhere.Nottingham Forest are keen on signing the Swede and have already submitted an initial £38 million bid, which falls well below Spurs’ valuation and was swiftly rejected.Nonetheless, the Tricky Trees are expected to return with an improved offer and are said to be preparing a new bid worth £45 million.Unfortunately for Forest, Newcastle have somewhat gazumped that plan, coming in with a £46m bid of their own for Bergvall, which was also rejected by Tottenham.Photo by Sebastian Widmann – UEFA/UEFA via Getty ImagesTottenham monitoring Arthur Vermeeren as transfer decision nearsSpurs are not keen on letting the midfielder leave and are holding out for a valuation of around £50 million. It remains to be seen whether Forest or Newcastle will meet that asking price.However, according to FussballDaten, Tottenham are believed to have now set their sights on another young midfielder.The player in question is RB Leipzig’s Arthur Vermeeren, who is 21 years old. It is explained that the Bundesliga side is open to selling the youngster, who is valued at €30 million (£26 million).Vermeeren managed no goals and one assist in 20 Bundesliga appearances last season.Spurs move for Vermeeren appears unlikelyIt is explained that, even though the midfielder is highly talented, Leipzig believes his decision-making is not yet up to the required standard and that he is still adapting to the intensity of German football.Regardless, he continues to have a host of suitors as the German side looks to offload him. It is claimed that clubs from Turkey and Spain are also monitoring his situation, although no specific names have been mentioned.As for Tottenham, it remains rather unlikely that they will make a move after recently completing the big-money signings of Sandro Tonali and Mateus Fernandes.A move to Spurs may also not benefit the youngster’s development, as he would be unlikely to receive regular game time.READ MORE: Four Tottenham academy starlets spotted in pre-season training with Roberto De ZerbiThe post Tottenham monitor £26 million midfielder after rejecting £46m Lucas Bergvall bid appeared first on Spurs Web.
