City stretched their lead on the best of the Premier League desk to 11 issues with a 2-1 victory at Old Trafford the day prior to this.
Mourinho took over from Van Gaal in 2016 after the Dutchman led United to the FA Cup.
The former Barcelona and Bayern Munich supervisor used to be incessantly criticised all over his time at Old Trafford for enforcing a gradual and robot taste of soccer.
But his predecessor has just lately been scrutinised for a similar philosophy compared to City.
And that has ended in Van Gaal taking a swipe at his predecessor, mentioning Mourinho’s way is much more dull than what he used to be criticised for.
“I would rather watch City play than United,” Van Gaal advised the Mirror.
“You want high quality in a squad and it is transparent City have a greater squad.
“If you question me how did I do at United, I can say it used to be my absolute best 12 months ever, given the instances I used to be operating below.
“We performed soccer that used to be slightly alright. But it is not soccer this is favored in England.
“And but, at the moment, taking a look at United, I’ve to conclude Mourinho isn’t being criticised whilst it is way more dull soccer.
“What United produce now could be defensive soccer. I all the time performed attacking soccer. The evidence is that the opposition had been all the time parking the bus.
“They don’t do this now as a result of Jose Mourinho performs so defensive.”
