The final of the Fantasy Premier League Cup is set to be a wide-open affair, with a number of differentials in play for both teams.
Both are riding high in the overall rankings, with Everton fan Mithun in 1,558th place and Ricky at 4,126th.
But the pair have taken notably different routes to the final and currently have just five of the same players in their squads.
That means there will be a number of players who could make all the difference in their head-to-head duel.
After all, a late goal from Robertson decided a dramatic FPL Cup final last season.
A move to Sterling would negate the possible impact of one of his rival's key stars, but Mithun will have to take a transfer hit to find the funds.
Ultimately, the tie could be decided by Southampton players.
Saints have a promising home fixture with Huddersfield Town.
Whatever happens, the contrasting squads of the two FPL Cup finalists will make Sunday’s showdown a thriller.
