Stevens started in Villa's 3-0 second round League Cup win over Tranmere Rovers and also came off the bench in the fourth-round tie against Swindon Town.
Stevens made his full league debut for Villa against Manchester United - an experience he admits he will never forget.
As a youngster, Stevens began his career with University College Dublin before moving to St Patrick's Athletic where he established himself as first choice left-back.
He made six appearances in the 2009-2010 UEFA Europa League as Pats advanced through two rounds to the play-off round.
Stevens signed for Shamrock Rovers in December 2009 and capped off his first League of Ireland season by winning his first title as Shamrock won the league title on the final day of the season.
He repeated this success in 2011 and also won the All Ireland Setanta Cup.
In 2011-2012, Stevens was part of Rovers' first ever UEFA Europa League clash and made 15 appearances in European competition over a two year period.
He capped off a memorable year by winning the PFAI Young Player of the Year.
