There are a number of leagues that are handed major upgrades across the month-long promotion, with the Premier League the most recent.
Indeed, those upgraded players are set to stay in packs until 6pm on Friday 13th May, when the TOTS will click over to the German top-flight.
Players can get their hands on TOTS cards in a number of ways: buying them on the transfer market, getting them via packs, unlocking them through objectives or completing Squad Building Challenges.
Kostic has been an excellent player for Eintracht Frankfurt this season, with the club reaching the Europa League final, although they have perhaps been less successful in the league, where they currently sit 12th.
And the Serbia international is set to be included in the TOTS when it goes live.
Leaks Confirm Incredible Bundesliga TOTS Filip Kostic Card
The Bundesliga TOTS is fan-voted and supporters have clearly been impressed by Kostic’s performances, placing him in the team.
And he is set to have a remarkable upgrade, too.
Kostic will have a 90 overall rating, along with a blend of attributes that are going to make him a nightmare for opposition defences.
He is set to have 95 pace, 91 dribbling, 87 shooting, 90 passing, 87 physical and 75 defending.
That is a remarkable left midfielder and is also a player who could operate as an attacking midfielder or even as a striker.
He has real strength, genuine pace, and these stats can be further boosted by the right chemistry style.
He may not be the single most expensive player in the Bundesliga TOTS but he will surely be highly sought-after, such is his ability.
He will be available in packs from 6pm GMT on Friday 13th May.
