An Individual Player Mentality Calculator for Football Manager 2020

Back in FM2018 I build a calculator to work out each individual player Mentality within a tactic, which at the time was driven by player Duty, some Team Instructions, Team Shape and Team Mentality. It was no easy feat. Each player mentality ranged from 1-20 and could change based on a number of variables. It was no wonder people struggled to understand it.

With FM19 things got a whole lot easier. Not only was Team Shape determined by the Duty of the players on the pitch, rather than being a variable you could select, but the player Mentality was given one of seven labels, rather than being a value between 1-20.

A player’s Mentality affects their attitude on the pitch in relation to balancing their attacking and defensive duties within the overall framework of the Team Mentality. Players are afforded a more attacking approach with a Mentality closer to the maximum, whilst a more defensive outlook is taken when it is set closer to the minimum end of the scale.

A players Mentality ranges from: Very Defensive > Defensive > Cautious > Balanced > Positive > Attacking > Very Attacking

I try to think of Mentality in terms of risk. The higher the Mentality — and that goes for both the player and the team overall — the higher the risk that will be taken. There is so much that goes into a tactic that I cannot possibly put it all here, however, what I feel is lacking is the ability to see every player Mentality on the pitch for any given tactic.

The below calculator will allow you to see each individual player Mentality, depending on the Role (Inside Forwards only) Duty, Team Instructions, and Team Mentality you select. Everything that can affect his Mentality is selectable below.


Please note, it might take a second or two for the Mentality values to show. Until I can convert this to something more web friendly, I’m stuck with Excel for now, which isn’t the quickest.

If you spot anything out of the ordinary with this calculator, please do let me know and I’ll get an update out as quickly as possible!

  1. Hi Oliver,

    There seems to be a glitch with the fullback mentalities. Using overall positive mentality, overlap on both sides, both FBs on attack duty, results in the RB with an ‘attacking’ mentality while the LB is ‘very attacking’. In game, both players have the same ‘attacking’ mentality – which is what you’d expect since they’re set up the same way.

    Also, if you switch both backs to ‘support’ their mentality drops a notch – ie, the LB goes to ‘attacking’ while the RB goes to ‘positive’ – but in game they both retain individual mentalities of ‘attacking’.

    Hope this helps in some way. Keep up the good work!

    1. Hey Warlock, thanks for the message.

      Yeah, that’s my bad. There are over 1,000 variables with this, I made a slight error. When I copied over the code for the LB to the RB, I forgot to have it look for ‘overlap right’, so it was slightly wrong as it was still looking at the instructions for the LB. I’ve published an update to the calculator now so hopefully, it’s all working properly. Give me a shout if you spot anything else out of the ordinary.

  2. This is great, just like the old calculator, thanks!

    Is it possible to make the “timeout” or whatever it is a lot longer? It seems like if you leave this for 5 minutes and then go back to change one role, you have to re-enter them all as it resets the entire sheet. Would be great if that could be turned off or tuned down. Either way this is awesome though.

    1. I just checked and there’s no ‘time out’ setting that I can see on this. I’ll keep digging, but I’m not sure if this is a browser thing rather than something related to the sheet. If you have any ideas, please let me know and I’ll look into it.

  3. Thanks – this was really useful. I never released that the ‘Overlap’ function reduced your wingers mentality and increased the fullbacks! Obvious now, but good to see exactly what it did. Also useful to see the impact of ‘focus play thought middle / down x flank’ etc!
