Haaland scored a goal every 79 minutes in his first season as City won the Treble – the Premier League, Champions League and FA Cup – in 2022-23.
That rate decelerated to one every 98 minutes last season and stands at one every 118 this campaign, with City enduring a difficult spell of just one win in 13 games between 30 October and 26 December.
Despite those declining numbers, Shearer says Haaland is “too good a player” for defenders to have “found him out”.
“He is good at everything – quick, good in the air, very, very good finisher – and when you have players around you who are going to create a lot of chances, it has been a dream team to play in,” said Shearer.
“He’s normal, when he goes three or four games without scoring, he is bigger news than anyone else because of how good he is. He is used to that and it won’t affect him. There are a tonne more goals to come from him.”
Shearer says there is “surprise” at the length of the deal but it is “good news” for the Premier League.
“We want the best product, there is no doubt about that,” said Shearer.
“You would not sign an extension to your contract of that length if you weren’t really, really happy and knowing you could go and achieve bigger things.
“This contract does not mean he is guaranteed to stay.
“I would be surprised if he was at City when he is 34, when this new contract ends, but this means they can hold on to him for longer, and no-one can come and get him for cheap if he decides he wants to leave.”
The striker’s renewal comes as City await the outcome of the Premier League’s case against them, examining alleged breaches of financial rules.
The club, who could face a huge sanction if found guilty, have denied the 115 charges levelled against them.
