Out of curiosity I decided to give this tactic a spin 10 games in to the season 19/20 with everton who I have won the league twice and champions league once. I have a team full of young 4.5 star regens who are not at their peek yet.
It was not far of proficient from the tactic I was using so was hopeful. My team had lots to adgust with Tempo though.
I lost my first game to Spurs 3-0 then went on to win 8 of my next 9 with an average of 2.7 goals per game usually 3-0 or 3-1. Bigist win was 8-0 against Grasshopper in the CL group stage.
I really like the attacking build up play to this tactic and scores some really fantastic goals. It creats great performaces from my wingers and WOW Barbosa has scored 10 from 8 since the change. Teams that counter attack can be a problem but hey if I am scoring more than them I dont care. Shadow Striker is a silent assain with this tactic I like it a lot, chips in with the odd goal and builds up play well from the centre. CWB are great, Bains is still scoring and assisting like crazy at 34 although I do have an amazing Brazilian regen to take over the helm.
I will be sticking with this for the rest of the season as I think it could win me the league. I was struggling big time against Chelsea in all previous meetings. I just beat them 4-2. Also beat Liverpool 4-2 another boggey team.
Cheers for the Tactic mate best one on FM 14 I have tried!
PS Hope I go on a 100% season like you have.
