What would have happened if Manchester City manager Pep Guardiola hadn't chosen to substitute Erling Haaland, who always finds a way to put the game beyond doubt? 

The Norwegian striker netted five goals against RB Leipzig on Tuesday but was taken off in the 63rd minute of the Champions League tie before he could get a history-making double hat-trick. Facing Championship leaders Burnley on Saturday, Haaland bagged his second hat-trick in five days before being subbed off again around the hour mark. 

Who knows how many more goals Haaland would have smashed in if he had played every single minute for the English giants?

"I took him off because I didn't want him breaking records," joked Guardiola after City's 6-0 FA Cup quarterfinal demolition of Burnley. "I always want to punish my players… I don't know the numbers, I don't know what the record is, but he is going to have a problem because every game people will expect him to score three or four goals." 

There is growing sense that Haaland could be the victim of great expectations, but his goal-scoring statistics are beyond belief.

The 22-year-old has now scored six hat-tricks this season in all competitions. No other player from Europe's top five leagues has more than two during this campaign.  

It's now 42 goals in 37 appearances for the formidable goal machine since he joined from Borussia Dortmund last summer. That is just two short of the record of 44 shared by Mohamed Salah and Ruud van Nistelrooy in the Premier League era. 

He is also just the sixth player in Premier League history to score at least 40 goals in all competitions in a season, joining Nistelrooy, Salah, Cristiano Ronaldo, Andy Cole and Harry Kane.

Guardiola's counterpart Vincent Kompany could only marvel at Haaland. "I played against the best of my era. But players like that, even the best defenders struggle because they find a way," observed the Burnley boss, who had captained City during a trophy-laden career. 

"Erling will always find a way and he continues to improve. You only have to look at his goals record, but his game has already improved from six months ago. He's going to be one of the greats, this is not something you experience very often. He looks like a superstar who is willing to improve and that is exciting to see."

The admiration was echoed by Premier League record goalscorer Alan Shearer. "Haaland is a beast," he said on Match of the Day. "He is a goal scoring machine. He lives and breathes goals.

"If he doesn't score he doesn't sleep at night. He wants another one, then another one, then another one... He's fantastic, and this team must be a dream with the chances they create. He might get 50 goals, maybe even 60. It's bonkers." 

At his current rate, Haaland can certainly reach 60 and equal the all-time goal-scoring record in a single league season set by Everton legend Dixie Dean, who achieved the feat in 1927/28. 

Later in the day in Italy, Zlatan Ibrahimovic became the oldest scorer in Serie A history when he converted a penalty in first-half stoppage time during AC Milan's 3-1 defeat to Udinese. 

The Swedish veteran, who drove Milan to win the Serie A title last season, has just returned from a serious anterior cruciate ligament injury. At 41 years and 166 days old, Ibrahimovic has overtaken Alessandro Costacurta, who also held the record from his Milan stint.
