It was the inevitable reaction to feeble title challenges that saw Guardiola's City finish 15 points behind the victorious Chelsea side in third place and Mourinho's United drift over the line nine points further adrift.
The Hammers' last win over United was a 3-2 Premier League victory in May 2016, which was also the final game at Upton Park.
Since the end of last season, transfer records have been shattered across the country as over one billion pounds has changed hands in a frenzy that could well set a new high for a single window.
"When I was young I was doing the same".
"In my other clubs what I had was more players scoring goals", he said.
Personally, I believe they'll top their previous achievement.
"I don't there's extra pressure on me".
Stock markets lower, gold price continues to rise amid political tensions
The CBOE Volatility Index, a barometer of expected near-term stock market volatility, closed at its highest since the election. On the currency markets, the pound slipped 0.1% against the dollar to $1.2968 but rose 0.1% against the euro to 1.1034 euros.
Premier League previews and pundit predictions are awash in the media this morning ahead of the big kick-off.
Whilst Premier League teams have no problems attracting quality players, it is now time for them to upgrade their tactics.
"Of course [Guardiola being in charge] had an influence on me".
And that's that - not one transfer rumour in this column - surely a first?
"I'm happy with the club's efforts".
I think I'm the coach of this team.
But winning the financial backing of Newcastle owner Mike Ashley has proved much tougher and Newcastle's travails in the transfer market over the last two months threaten to lead to a messy divorce. City lack depth at centre-back where Vincent Kompany, John Stones and Nicolás Otamendi are the only senior options.
Charlottesville: State of emergency over USA far-right rally
In the days leading up to Saturday's planned rally, there had been some back-and-forth about where it would be held. However, that's only deterred a small fraction of the thousands of people expected to attend "Unite the Right".
Unlike last season, City should be expected to line-up with as many formations as you may think especially now that Pep finally has very good squad depth going forward.
Ederson said he settled in quickly at the Etihad Stadium and said he spoke to fellow Brazilians Fernandinho and Gabriel Jesus before completing the move.
Yet perhaps the Premier League's most memorable moment - certainly the most crucial when it comes to marketing and its ongoing credibility - came just two years ago, when Claudio Ranieri's relegation-fancied Leicester staggered the country by waltzing away with the league title with the kind of ease their striker Jamie Vardy usually reserves for vodka and a bag of Skittles.
I see West Ham as a mid-table side looking upwards, but it is asking a lot for them to get anything at Old Trafford. Guardiola has been foot flawless all summer and made big additions to his squad early and often. The beginning of the season has been great. No, I'm just myself.
The midfield looks fairly well stacked as Yaya Touré, David Silva, Kevin De Bruyne, Leroy Sané, Raheem Sterling and, when fit again, Ilkay Gundogan will provide plenty of ammunition for the strikers to feed off. They told me this is a really big club with a nice history.
Arsenal also embarks on a new campaign uncertain whether it will hold onto a key member of its squad.
