Lampard will be Chelsea captain on the night as they take on German giants Bayern Munich at the Allianz Arena.
But a win for the west London side will mean that Redknapp's Tottenham will not feature in the competition next season despite finishing fourth in the Premier League.
Redknapp said: "I want Bayern to beat Chelsea, whether Frank plays or not.
"He knows there's no love lost. My allegiance is Tottenham only. I want Tottenham in the Champions League next year.
"I was always going to the final. I've been looking forward to it for ages. I'd rather be there than watching it on TV.
"We can't do any more now, but I couldn't be more pleased with what we've done this season.
"If people get carried away with what Tottenham should achieve, they need a reality check."
