The Red Devils are in second place in the Premier League table but Manchester United have scored less goals than Manchester City and Liverpool FC.
Mourinho’s side have often attracted criticism for their negative approach to their games against their biggest domestic rivals.
Manchester United are 16 points behind Premier League champions Manchester City after their 1-0 loss to West Brom earlier this month handed the title to Pep Guardiola’s team.
The Red Devils suffered a surprise 2-1 loss to La Liga side Sevilla in the Champions League round of 16, while Manchester United suffered a 2-1 defeat by Bristol City in the League Cup last four.
The retired England international was part of the Arsenal team that came up against Sir Alex Ferguson’s great Manchester United teams in the 1990s and early 2000s.
Former Arsenal star Parlour admitted that Manchester United are unrecognisable from the club that produced thrilling football under Ferguson.
“Manchester United have had so many great teams over the years, and look at this team – it doesn’t even compare,” Parlour told Sky Sports.
“In my era, Scholes, Keane, Giggs. I know football has changed, but it was always quick football with United back then. It’s a lot slower now. There have been some really poor performances, West Brom sticks out, where the build-up was so slow.
“Man United fans will be looking at it thinking: ‘We need to be better.’ But if they do win the FA Cup it’ll be three trophies in two years, and that’s not a bad result.”
Manchester United signed Chile international Alexis Sanchez in a swap deal from Arsenal in the January transfer window to bolster their attacking options.
The Red Devils haven’t won the Premier League title since 2013.
