Never really looked into the Gens tab on the webapp before. Pretty cool! I have a few Arsenal IFs from this and some from this year too. The best thing is seeing how my addiction rose. It says I started playing in 11 but no cards from that year appear, 12 has a small few, 13 it gets bigger, 14 bigger still and the last year I seem to have a million untradeables! Last year was the first year I cut down at then end to buy as many top rated Arsenal cards as possible.
I think I only first used any IF cards in 15. My favourite non Arsenal card in 15 was SIF Chikhaoui and in 16 it's TOTS Ben Yedder so they will be added to my Arsenal team.
All in all it's a pretty cool feature but it would be great to have some kind of Gens cup, although I guess that's a big can of licensing worms!
