Ryan Giggs countered Zlatan Ibrahimovic's criticism of the Class of '92 on Tuesday.
Ibrahimovic, a former Manchester United striker, argued that public complaints from Red Devils legends and their comparisons to Sir Alex Ferguson's trophy-laden regime have hindered progression at the club.
However, Giggs suggested his status - he made a club-record 963 appearances for United - and that of his fellow 1992 academy graduates have earned them a right to air their views.
"Only Nicky (Butt) is connected with the club now, but when you play over 2000 games (actually 3,450 overall) between us, we are going to have an opinion," Wales boss Giggs said, as reported by ESPN FC's Mark Ogden.
"Sometimes it's positive, sometimes negative, but it doesn't have an effect on results. We are supporters. That's what football is about, having different opinions."
Giggs added sarcastically: "But he (Ibrahimovic) obviously knows more about the club than us."
Gary Neville and Paul Scholes have been particularly outspoken on United, notably delivering withering assessments of the boardroom and ex-manager Jose Mourinho.
Ibrahimovic, who represented United for less than two seasons before he officially left for the LA Galaxy in March 2018, also stated criticism from ex-players piled pressure on Paul Pogba, a friend and the club's record signing since he returned from Juventus in 2016.
Giggs was asked for his reaction to Ibrahimovic's comments ahead of Wales' friendly against Trinidad and Tobago in Wrexham on Wednesday.
