From what I've seen about Haaland's performances for Manchester City in big games is that he doesn't fare well in big games when he plays in them. The same situation that occurred in the Supa Cup matchup against Sevilla, where Haaland made no attempt to score, also transpired in the champions league last season. Is when Manchester City plays against small teams and during games when De Bruyne is there will you find Haaland performing wonders by scoring beautiful goals.
On Saturday, Manchester City is going to play against Newcastle, let's see whether Haaland would make any attempt to score. As for me, he is going to play well in that match because it is going to be a big game.
You are right, Haaland does not play well in big matches. He probably prefers to play in a pressure free manner. Can't play well under extra pressure. We haven't seen a better performance from Haaland in the semi-finals and finals of the Champions League. However, with De Bruyne, Silva and Gundogon in the squad, despite Haaland's lackluster performance, Manchester City's overall performance was very good last season.
Newcastle's match is very important. There are no big star players in the Newcastle team. But the bonding between the players in this team is the strongest of any team in the Premier League. And so, without De Bruyne and Silva, it cannot be said for sure whether Manchester City's performance will be good in this match. I wouldn't be surprised if Newcastle wins this match.
Regardless of how Haaland performed in the Champions League semi-finals and final last season,I think it would be wise to appreciate his goalscoring record. Haaland played 11 matches last season with Manchester City in the Champions League, and he managed to score 12 goals in 11 matches. Don't you think that's great?
After all, Pep Guardiola doesn't play a game strategy around Haaland so we can see all the players who play are involved in attack. Haaland is a target man, but almost anyone can score goals because Pep Guardiola has that scheme in building attacks instead of relying on one player.
