Tim Sherwood's side won the quarter-final at Villa Park 2-0 to ensure a trip to Wembley for the first time in five years.
However, the victory has been overshadowed by some of the scenes involving supporters at Villa Park.
Some visiting supporters to Villa Park appeared to rip out their plastic seats and used them as missiles which were hurled at Aston Villa supporters directly below them.
There were also two pitch invasions before the final whistle and then fans went onto the turf in larger numbers once a 2-0 win for the home side was confirmed by the ending of the match.
Fabian Delph, scorer of one of the Villa goals that ensured his team's place at Wembley for a semi-final, described the scenes as "scary" and claimed he was bitten.
"It was dangerous," said the midfielder. "People tried to kiss me and were biting me." He also added that it was "very, very scary".
