Ndidi, Bruno Guimarães, Eriksen. If a LW, Everton Soares. Ndidi = 70 million? Bruno Guimarães, Everton = 35 million each one. Eriksen = Free or low cost. Leno Bellerin Saliba Luiz Tierney Ndidi (Torreira) Guendouzi (Willock) Eriksen (Bruno Guimarães) Pepe (Nelson/Saka) Aubameyang (Lacazette) Everton (Martinelli) 4-3-3 could be a 4-2-3-1 too with either Willock, Özil if he continues or Eriksen as AM. I would try to develop Martinelli, I think he is a potential world class (or even franchise) player. But Everton is perhaps the best player in Brazil today, and for me he should be already in Europe, he is only 23 and still improving (whoscored ratings as starter 7.1 in 2017, 7.4 in 2018 now 7.7 in 2019)... eventually could be a world class too, but even if not, I think he could be very useful player if you are looking for someone on the left for a relatively low cost in today's market. Bruno Guimarães (22) is doing better than Arthur (of Barcelona) at the same age, according to Sofascore ratings, and is a player who offers quality, distribution and order in Arsenal's midfield , he could eventually be a world class player in his position as well, role of Deep Lying Playmaker, a bit of B2B too. Could be a good bet for his price. BG and Everton are in the radar of the Brazilian NT for the next 10 years, if all goes right. Eriksen is proven and is quality, could offer a more offensive option in the midfield-attack. Ndidi seems to be a defensive monster. These are proven in the Premier. They need no further explanation. A new coach for sure and perhaps a new RB.
