The England midfielder stresses that the team have to take each game as it comes amid their relegation battle.
Saturday night’s 2-0 win over Midlands rivals West Bromwich Albion saw Villa book a place at Wembley Stadium for the competition’s semi-final stage next month, where a tie against either Liverpool or Blackburn Rovers awaits.
The club’s successful cup run has been a welcome distraction from their dismal league form, with a record of just three wins in 24 top-flight matches landing them in a relegation battle with 10 games remaining.
A 2-1 win in the opening clash of their West Brom double-header saw Tim Sherwood pick up his first three points since taking charge, however, and also lifted the team out of the drop zone into 17th place.
Consecutive victories have now given the atmosphere around the club a massive boost ahead of the weekend’s trip to Sunderland, where Delph insists the focus will be 100 per cent switched to the survival fight.
“We're not thinking about the semi-final,” he affirmed. “We're focused on is Sunderland and taking each game as it comes.
“We’ve been there [the Stadium of Light] a lot of times and they’ve got good fans there, but we’re going there to get three points.
“The gaffer will have a game plan for that match and if we stick to it then I’m sure we’ll get the win.”
Delph netted just his first goal of the season in the FA Cup win over West Brom, while also captaining the side in the absence of injured skipper Ron Vlaar.
After last season’s breakout, it’s been a somewhat disrupted campaign for the England international due to injuries and suspension, but he now looks to be coming into form at just the right time.
