Bringing in Onana, Caicedo, Mount and proper number 9 would totally transform this team to a big read machine again. So much passion, power, pressing and fighting added in 1 year (counting this window and the last summer).
Just imagine putting up (on paper something like):
-----------------Onana
---AWB Varane Martinez Shaw
----------------Casemiro
-----------Mount Caicedo
------------------Bruno
-------- -Rashford Höjlund
and it would probably more be like
-------------------Onana
-----AWB Varane Martinez Shaw
----------Caicedo Casemiro
-------Mount Bruno Rashford
------------------Höjlund
I can see a lot of teams having problems betting this team, not claiming we will win the league or CL but i don´t see us loosing 7-0 with this team at least just to make a point. This team has a playing GK, a world CB partnership, one of the best LBs + a RB that is impossible to dribble past and showed some glints of a better offense last months. A central midfield with so much power, passing, press, energy and passion + technical and ball carrying ability with great chance creating in to the final third in both Bruno and Mount and hopefully a Rashford that will keep scoring 30+ goals every season together with a huge talent in Höjlund that is fast, strong, good with both right and left leg and in the air and only 20 years.
I might just be dreaming, but i see this a team that can with little time together be 2-3 signings from competing for the PL in 1-2 years if we also get Sheikh Jassim to back up ETH and appoint right people to take care of the club.
