Rees Greenwood, Tommy Robson and George Honeyman all made their first Premier League appearances as the season came to a close.
Speaking about the debutants collectively, Allardyce told the media post-match they all played "very well indeed" However, when asked to state which youngster stood out the most, the 61-year-old named Greenwood as the player who offered the "most in terms of his contribution".
Allardyce also claimed left back Robson looked "very comfortable" as he played the whole 90 minutes.
The reason for the changes
Only Lamine Kone and DeAndre Yedlin kept their place in the line up yesterday but Allardyce had his say as to why he chose to make nine changes from the team that beat Everton 3-0 during the week.
Allardyce said the reason behind the rotation was down to the players working so hard to keep Sunderland in the top flight in the last few weeks. These players had "no need to come out and exert themselves anymore".
Allardyce went on to say the emphasis was on the squad members who had not played this season to show "what they have got" for next season.
Sunderland ended their season in fantastic form with 12 points from the last six games. They were unlucky to not end their campaign with an away win yesterday, after Duncan Watmore had a goal ruled out and Dame N'Doye had a diving header ruled offside. Troy Deeney also scored a controversial penalty.
Allardyce admitted it was "very important" to finish undefeated, and claimed it was a good end to what has been a "difficult season".
Sunderland will now prepare for another season in the top flight, and we may be seeing more of the youth products if they earn another shot next year.
