Gus Poyet says keeping Sunderland in the Premier League will remain his priority ahead of March's trip to Wembley.
Wednesday's Capital One Cup shoot-out success at Manchester United means Poyet's side will contest the club's first domestic cup final in 22 years, discounting play-offs.
And victory over non-league Kidderminster on Saturday will put Poyet's side in the last 16 of the FA Cup.
The Uruguayan is serious about shocking Manchester City at Wembley on March 2, but Sunderland remain in the bottom three of the league.
And he said: "The challenge is to stay in the Premier League. That was my challenge when I got the job and it was clear from the beginning.
"Now we are lucky enough to find ourselves in a great position in a cup competition to go and play a final, and we need to try to do everything possible to win it.
"People are talking to me about 'the treble' - staying up and winning the two cups. Now it's a new treble. Normally it's winning everything, but staying up has become like a trophy.
"I am realistic - I am realistic in the Capital One Cup as well because the opposition is not an easy one. Right now, they are on fire and anything can happen, so we need to be really strong on the day."
