Andreas Pereira and Axel Tuanzebe have signed new contracts with Premier League side Manchester United, the club has confirmed.
Following successive loan spells at La-Liga clubs Granada and Valencia, Pereira made 22 appearances across all competitions for United last season.
Pereira made 16 of those appearances under Ole Gunnar Solskjaer, having failed to establish himself during Jose Mourinho's tenure.
United triggered an option on Pereira's previous contract in March, extending the midfielder's deal to June 2020.
And the club has now tied the 23-year-old down to fresh terms, committing him to the Old Trafford outfit until June 2023, with an option for a further year.
"I have spent so long in Manchester that I now regard the city and the club as my home and I'm extremely happy to continue my career here," Pereira, who joined United's academy in the 2011-12 season, told the club's official website.
"The manager has shown great faith in me and I can't wait to get this campaign started under him."
Solskjaer added: "Andreas is another player brought through our academy that understands what it means to play for United.
"He came from another country but quickly understood the values of playing for this club and doesn't take it for granted."
Tuanzebe, 21, has signed a three-year deal, extending his stay at Old Trafford until 2022, with an option for an additional year.
"I have grown up at United and it has always been a big part of my life and my family's life," Tuanzebe, who can play at centre-back, full-back or in midfield, told United's official website.
"I appreciate the trust that the club has in me and I want to repay that with my performances on the pitch.
Tuanzebe became a key figure for Villa last term, making 28 Championship appearances as Dean Smith's side secured promotion to the top flight.
Pereira and Tuanzebe renewals follow on from Marcus Rashford pledging his future to United, with the England striker having signed a four-year deal with an option for a further year on Monday.
United has also been busy in the transfer market, with Daniel James' arrival from Swansea City having been followed by the signing of Aaron Wan-Bissaka from Crystal Palace for a reported £45million fee, while Leicester City is rumoured to have rejected a bid for Harry Maguire.
Newcastle United midfielder Sean Longstaff continues to be linked with a move to Old Trafford, while doubt remains over the futures of Paul Pogba, Alexis Sanchez and Romelu Lukaku.
