Erling Haaland bagged another brace as Manchester City ended Bournemouth’s eight game unbeaten streak at the Etihad Stadium.The Norwegian’s two first half goals, both assisted by Rayan Cherki, either side of a Tyler Adams equaliser contributed to an enthralling first half, where both teams played entertaining, attack minded football.The second period was cagier, but Nico O’Reilly’s first goal of the season, a crisp left footed strike from the edge of the area, put a seal on a well deserved victory for the Blues.Here are three things we learned as City beat the Cherries:Haaland x Cherki is a winning comboThere was something so refreshing about watching Haaland and Cherki operating together; they just seem to understand each other and compliment each other’s games so well.The French midfielder is always looking to play forward, and seeks to get involved in the game too by frequently showing for the ball.Haaland, meanwhile, loves to peel off the last defender onto Cherki’s passes and get in behind the backline.He did that twice in the first half and finished coolly to put City ahead, but a lot of credit must go to Cherki for finding the Norwegian at the first possible opportunity.Kevin de Bruyne’s departure means Haaland is shorter of service than ever before, but Cherki’s electric start at City is helping to bridge the creativity gulf. Narrow wingers suits the personnelAlmost every one of City’s attackers suits operating in the pockets, so it seems bizarre to me that Guardiola doesn’t choose to utilise his wingers this way more often.Cherki looked at home in this area, and Phil Foden also plays well there when not playing in the middle.Jeremy Doku has taken a step up this season and is particularly impressive in central areas, whilst Omar Marmoush and Oscar Bobb’s skill sets also suit this tactic.At full back, O’Reilly and Rayan Ait-Nouri are good crossers and attacking minded players who can contribute lots on the left hand side, whilst Matheus Nunes offers the same on the right.Rico Lewis can also thrive in pockets, whilst Abdukodir Khusanov’s pace means he could also potentially fit into this system as a right back.Guardiola this season has shown his willingness to adapt his system to suit that of his players, and the narrow attack with creative bodies surrounding Haaland is one that’s really getting the best out of this City team right now.Savinho criticism is fair, but shouldn’t overshadow the resultAs always, much of the fans’ frustration seems to be aimed at Savinho.The Brazilian came on and left a lot to be desired in his cameo on the pitch, giving the ball away really cheaply on at least three occasions.I’m personally of the opinion that he’s not as good as Foden, Cherki, Doku, Bobb, or Marmoush, and that he gets too much playing time based off of underwhelming performances.But I also think that in the context of yesterday’s game, where Haaland scored yet another brace, Cherki and Foden shined, Rodri made his return from injury, Nico Gonzalez was excellent again and O’Reilly and Nunes showed their class, as well as generally good performances from every player individually, that Savinho shouldn’t be the centre of attention.He played well against Villarreal and recorded an assist recently against Everton. He’s a good talent, and can only get better under Guardiola.Turning all of the post match chatter onto him seems to be a bit undermining of the excellent win for City, and perhaps a tad unfair on a young player in Savinho too.
