"It is not a case of because we are playing them tonight, we will know how to play them in the cup final," he noted in speaking to the official FA website.
"Each team has four or five games before then."
Platt went on to point out that Wigan continue to fight the threat of relegation from the Premier League, a reality that will likely monopolise the Latics' attention until the cup final draws near.
"Roberto Martinez is a good manager and I am sure they are looking at the next four or five games and thinking, 'If we can get away from that relegation threat, then we can enjoy the day'," he continued.
"It doesn't take the shine off the day but retaining Premier League status for them is paramount.
"I am sure if they have it in the bag by then, they will be delighted and they can go and enjoy a Wembley cup final."
