One of the most wanted men is Gabriel Jesus.
Brazilian Jesus, who helped Manchester City to four titles in five-and-a-half years, attracted interest from a host of clubs in England and beyond before he moved toArsenal.
The 25-year-old is seen as a major boost to the attacking options of the club. Can he help the north Londoners return to the top flight?
95 goals in 236 appearances isn't a bad return for Jesus, who was never considered a prolific goal scorer.
With four titles, three League Cups and an FA Cup under his belt, he can empathise with the excitement of the fans of his former club.
With Mikel Arteta's young squad showing a lot of promise, one of their key deficiencies was in front of goal, scoring less than the four teams who finished above them.
Arteta relied on his younger players for goals, with England international Emile Smith Rowe adding 11 to his tally.
A closer look at Jesus' statistics suggests that he could provide the extra goals the team needs.
He has scored in 42% of his starts in the premier league, which is 13th highest in the competition's history.
He has an average of 159 minutes per goal, which is 14th best among players with 50 or more goals in the league.
Jesus brought more than just goals to Manchester City, with his work-rate and ability to play in various roles making him a key man for Guardiola.
He was a talisman for the title winning team and was often called upon to play. He won 76% of the time he played for City in the top-flight.
In his time at the club, Jesus assisted eight league goals and created more chances than any other player.
Jesus was aware that he would have had limited game time this coming season had he stayed, as he spent much of his time at City playing second fiddle to sergio aguero.
Is the Brazilian finally going to be a main man in the league?
Eddie Nketiah's only other option is as a main strikers, because of the lack of experience in the line-up.
I'm very happy. Kevin Campbell believes that Gabriel Jesus is a world-class player, but he wasn't used as much as he could have been.
Whenever the big games came around, he played, he started, and most of the time, he assisted or scored. Arteta has been working with him. He has a good idea of what kind of player he is. Jesus should be the main man at City because Haaland will be the main man there.
Jesus will get the club close to the top four according to Ray Parlour.
Is Jesus going to be as prolific a scorer as the team hopes for?
Stephen Kelly, an ex-Spurs and Republic of Ireland defender, said that Jesus is very similar to Laczacette. He's been playing in a team that is very creative.
Is it possible for him to score 20 goals this year? I don't think those goals will be met.
The new arrival from Manchester City doesn't have to score a lot of goals, according to Harry Symeou, from the Chronicles of a Gooner.
He said that Jesus will be a good fit. There is a need for a centre- forward. This was an option that was as good as what was available when it came to where the team wanted to go.
Gabriel Jesus is not going to score 25 goals in the premier league. That's not what the team wants. They want someone to get into double figures but still bring the best out of the attack as a group.
It would have been a completely different ball game if Laczacette had a lot of goals. He is coming in because he wants to add to the goal tally.

Mikel Arteta is familiar with what to expect from Gabriel Jesus.
Even if his goals output - 58 goals in 159 appearances - has been sporadic, the Brazilian feels like he's the replacement for Pierre-Emerick, who left for Barcelona in February.
If the way Jesus went about his work at City is any guide, he will fit into Arteta's team pattern more than any other player.
Jesus arrived from Palmeiras in January of last year.
At the time, he was only 19 - his signing had been completed a few months earlier but he remained in Brazil to complete their domestic campaign - and he performed so well, it was thought that he was a better fit for the team.
Jesus broke his foot after scoring three goals. The idea of selling him was thrown out the window when he started scoring again.
Even though Jesus was more direct and less tricky than the City team-mates, he preferred to play wide.
For the past two seasons, Jesus was the choice when it came to playing as a centre- forward. Arteta knows that moving someone into a position he doesn't like is not something he would want to do.
