Some of Sutton's fellow pundits have questioned whether the Swede can repeat his goalscoring form with Sporting CP in the Premier League.
"It's just typical isn't in that there is instant judgement and people are making their minds up on him after an hour," said Sutton on BBC Radio 5 Live's Monday Night Club. "When players move to a new club, some fit in better than others, but it takes them all a time to settle in.
"In the final third, it is about combinations and understanding of others so you know how they will link up with others. Gyokeres didn't get any service on Sunday. Bukayo Saka had a pretty poor game and Gabriel Martinelli didn't really look for him, so it is going to take time.
"No matter which way you want to look at the Portuguese league, his numbers were phenomenal and his finishing in the Champions League showed he is a pretty good striker.
"As a striker you need to get the opportunities so that understanding of one another should come the longer they train together and as the season goes on."
