to be honest if we want to challenge in Europe there must be a change in formation. in a 352 the only souce of creativity is pirlo vidal and pogba. we can't just rely on midfielders. an example to follow is Dortmund. what they did they spent money on talented 21,22,23, year old plaayers which showed that they had potential and intergrated them into the team.
look at how much they spent for their attack last season. Reus 17m Lewadolski 5m blaszczykowski 3m. Juve already have a top fordward number 9 like llorente and he can certainly score goals in Europe especially. we just need a few players that are going to be those vidal, pogba, reus type of investments and 1 world class player and we are set.
