Smith said: "He has been very important for the club over the last season, integral to us getting promoted last season.

"He won Player of the Year, Supporters' Player of the Year and Players' Player of the Year. He merited that contract and we want to keep the best players at Aston Villa.

"He is one of them, along with Jack Grealish who has a long-term contract.

"John, I feel, we can develop further and he is really looking forward to the season. He has earned it."

McGinn scored seven goals in all competitions and made 44 appearances after signing from Hibs for £2.75million.

He added: "I have loved every minute of my time at Aston Villa and I am delighted to commit myself to the club for the long term."

Smith confirmed their £130million spending spree was over and is happy with his forward line after the £22million club-record signing of Wesley from Club Brugge.

He said: "Yeah, we brought Wesley in, we have (Jonathan) Kodjia and (Keinan) Davis and Jota, Trezzy (Trezeguet) and (Anwar) El Ghazi, the way we played there are goals all over the pitch.

"There are a number of players who can score goals. We also have January to go and use funds if we need it."

Ahead of the trip to Tottenham Hotspur Stadium, club captain James Chester is out with a hamstring problem.

Summer buy from Manchester City Douglas Luiz is available after earning a work permit while Wesley, Matt Targett, Jota, Ezri Konsa and Trezeguet could all make their debuts.
