Newcastle 'close to our best' in win over Manchester City - Howe
Howe had tried numerous approaches.
The Newcastle United head coach previously deployed sides who pressed Manchester City aggressively. Other formations saw his team sitting back defensively. He experimented with multiple formations, all without positive results.
It reached the point where Howe was only partially joking when he stated "we don't have anything new left" before Saturday's match.
Yet he found an answer.
When Newcastle desperately needed a positive result, following a difficult loss at Brentford before the international break, The Newcastle management created a blueprint to finally defeat Guardiola's team.
And their planning proved successful following a 2-1 victory at an electric St James' Park marking Howe's initial Premier League success against Guardiola's side after 16 previous failures.
"I have extensive documentation of unsuccessful approaches against them, so I know what to avoid," Howe revealed. "Identifying successful tactics requires minimal documentation, but we learn from each experience and make adjustments. This was our process."
The foundation was established in the days following Newcastle's 3-1 defeat at Brentford this month.
Howe spent numerous hours examining game film, assessing training and searching for fixes to their up-and-down form.
Despite having fewer players available, Newcastle concentrated on regaining "their dynamism and physicality" during the break.
Several notable adjustments were implemented for Manchester City's visit.
Bruno Guimaraes was deployed centrally in midfield, a role previously held by Sandro Tonali, with returning defenders Lewis Hall and Tino Livramento making their first joint start since autumn and creating a significant difference.
Defender Fabian Schar earned his first league start since autumn, coming in for Sven Botman.
However, rather than implementing radical changes, Howe maintained his preferred 4-3-3 system and two of the three modifications to his starting lineup were essentially forced after Kieran Trippier and Anthony Gordon missed out through injury.
The majority of players who featured at Brentford and, indeed, in the damaging defeat at West Ham, were given opportunities to redeem themselves.
"I don't support the idea of tearing everything down," Howe stated. "Only in crisis situations would I consider drastic changes, which this isn't, and that's not my approach.
"I'm confident in identifying our best performers and aim to give them maximum chances to showcase their abilities through guidance and development opportunities."
The Magpies had secured just a single victory in 35 prior Premier League encounters with Manchester City
Nevertheless, adjustments were clearly necessary.
Only the struggling offenses of Wolves and Leeds had produced fewer goals than Newcastle this season.
New signing Nick Woltemade had seemed detached, with minimal attacking supply, particularly away from home.
While Woltemade was on international duty with Germany, Newcastle practiced varied attacking patterns around their striker including Barnes and Jacob Murphy, to enhance his performance when he rejoined the team.
The Magpies generated clear chances for Woltemade during the match, with the City keeper making three crucial saves.
However, while Newcastle previously relied too heavily on Woltemade, additional squad members have started making important contributions.
Especially Barnes.
Barnes wasted crucial opportunities before halftime - even missing from close range - and acknowledged he wasn't "the most appreciated player" at intermission.
But not only did Barnes open the scoring with an excellent effort from the edge of the area in the second half, he delivered the winner just minutes after Manchester City equalized through Ruben Dias.
Newcastle previously led against Arsenal, Brentford and West Ham only to ultimately lose.
However, they maintained composure when City drew level and during eight additional minutes.
This performance saw Newcastle dominate physical battles, winning more challenges and defensive actions.
While City dominated the ball, inevitably skewing the numbers, Newcastle defended resolutely with 36 clearances and limited City to only four accurate shots.
The defensive display caught the attention of ex-Newcastle player Jonathan Woodgate.
"Defensively they were outstanding, making it extremely challenging for City to exploit gaps in midfield," he told BBC Radio 5 Live. "Second half I considered them the superior team, consistently catching City on counter-attacks and ultimately scoring two magnificent goals by Barnes. What an entertaining match."
Nevertheless, is this outcome at a vibrant St James' Park truly astonishing?
Only City (13) have collected more home league wins than Newcastle (11) in the current season.
From the start of the previous campaign, Newcastle have recorded eight victories, two draws and only two defeats at home against top opponents including City, Arsenal, Liverpool, Chelsea, United and Spurs.
However, away from home, Newcastle haven't triumphed in the top flight since April.
This accounts for their position just one point clear of the bottom three prior to Saturday's important win.
"While I'd like to assert that supporters shouldn't affect player performance, it completely changes dynamics," Howe acknowledged. "We must determine how to transfer positive energy into our away performances when we lack crowd support.
"This problem requires our solution, whether through formation tweaks, selection alterations. Regardless of the approach, we need to commit to finding remedies."
