That is according to pundit and former Liverpool defender Jamie Carragher.
Jose Mourinho is having a tough time of it at present.
His side trail neighbours Manchester City by 15 points in the race for the Premier League.
And while Guardiola's men have played attractive, eye-catching football, Mourinho has been slated for his negative tactics.
And now Carragher has slammed the Portuguese coach, insisting his managerial counterpart in the blue half of Manchester has made City's squad far superior.
"If Pep Guardiola was in charge of the United squad I believe they would win the title," he told the Telegraph.

"Rewind to the start of this season and assess the head-to-head qualities of the United and City squads.
"Player-for-player, which would you argue was superior?
"Was Ederson considered better than David De Gea? Were City’s centre-backs Nicolas Otamendi and John Stones preferable to Eric Bailly and Phil Jones?
"Did United fans want Fernandinho or Nemanja Matic?

"How many United or England fans would have swapped Marcus Rashford for Raheem Sterling a year ago? And when Anthony Martial first arrived from Monaco, was his reputation greater than that of Leroy Sane when he joined City?
"We can go on throughout the respective lists.
"Where Mourinho sees players unable to execute his tactical blueprint, I believe Guardiola would have taken a different approach with a squad Mourinho believes needs reinforcing."
After United's 2-2 draw with Burnley on Boxing Day, Mourinho insisted his side have not spent enough money to compete with their title rivals.
The Red Devils have spent £286m since the Portuguese coach arrived at Old Trafford.
