It looks to me that Ole want to change the dressing room atmosphere, and on pitch attitude, more than to bring new stars that will bring more problems in already bad atmosphere. The problem with the team is that you can't sell deadwood, and even bigger that you can't have short term success. So, bringing young lads with a space to grow and be much better in a 2-3 years, is a good sign. One top player per window, and fixing holes in the team (RB, RW, CM) with players with right attitude is probably better than to gamble with stars that probably won't deliver. Look at Alexis, or Pogba, or Lukaku, or Mata. All brought some quality, but not what you expected for the money invested. On the other hand look at Fred or Lindelof who are from abroad, and needed one year at least to adapt. Not sure we have that one year now, so I guess, Ole wants kids from the league that won't need a year to adapt to PL. Not sure if the choice of the players is the right one (James, Longstaff, Rice,...), we will see if scouts did their job, but the direction is OK for me. Certainly, it is better bet than bringing players like Rodriguez or Dybala, that won't guarantee anything and would be paid in gold so you can't sell them later.
