I have decided that 4-2-4 would be the best approach for this team with 2 new additions to strengthen the team!
With this 4-2-4 I managed to go through the league season unbeaten winning 28 and drawing 6 having a points total of 90. I also won one of the Portugese domestic cups which meant I had one the a domestic double. The other domestic cup we were runners up after losing the final against Benfica. We also reached the Champions League semi finals but got knocked out by Manchester Untied but I have exceeded my own expectations already by reaching the semis.
