Villa boss Sherwood is a fan of attacking full-backs and has been thrilled with Richardson's all-action approach going-forward down the flank in claret and blue.
Richardson joined Villa in July 2014 and was initially seen as one of the three-man midfield options or a left winger under Paul Lambert and Roy Keane.
But when Sherwood arrived in February 2015, he quickly plumped for Richardson in a back four role.
He started the first nine games before having a spell on the bench as a substitute.
Richardson saw red in the 1-0 derby defeat to West Brom in December 2014 - a sending off that earned him a three game ban.
But he was out for longer as a calf injury meant he also missed an additional three matches.
When he did return to the starting line-up for a couple of games it was mixed emotions - as Villa saw off high-flying Bournemouth 2-1 and then went down 5-0 away at Arsenal.
He came off in Tim Sherwood's first game as manager against Stoke City with a hamstring problem and then sat out the next six games.
Richardson returned in the 3-3 draw with QPR and excelled in subsequent games against the likes of Tottenham, Liverpool in the FA Cup semi-final, Everton and West Ham.
He was looking doubtful for the FA Cup final against Arsenal but recovered from his calf injury to take his place in the lions line-up.
Richardson signed for Manchester United as a 17 year old from West Ham United in 2001.
He made 81 appearances in all competitions for the Red Devils, scoring 11 goals, and was part of the squad that won the Premier League title in 2006-07 and the League Cup in 2005-06.
He had a loan spell with West Bromwich Albion during his time at Old Trafford, playing a central part in keeping the Baggies in the Premier League in 2005.
He moved to Sunderland in July 2007 to link up with former teammate Keane, who was manager at the Stadium of Light.
He stayed on Wearside for five years, making 149 appearances in all competitions and scoring 15 goals, before moving back to London with Fulham in August 2012.
He made 48 appearances for the Cottagers, scoring six times.
Richardson has earned eight England caps, scoring twice on his debut against the USA - the second set up by Villa team-mate Joe Cole.
