The Gunners signing the France international in a £52m deal from Ligue 1 side Lyon last month to eclipse the £42.5m fee that Arsenal paid for Mesut Ozil in 2013.
Lacazette established himself as one of Ligue 1’s leading strikers over the past four or five seasons thanks to his prolific record with Lyon.
The 26-year-old scored 28 times in 31 games in the French top flight last season to take his tally to 100 goals in 201 appearances since breaking into Lyon’s first-team.
Lacazette will be tasked with providing the goals to fire Arsenal back into the Champions League after the Gunners finished in fifth place in the table last season.
Former Arsenal defender Groves is confident that Lacazette will repay his transfer fee at the Emirates Stadium.
“We’ve bought a proven goalscorer in Lacazette who, with the team we have, should be getting at least 20-25 goals this season,” Groves told bwin.
“He looks strong on the ball, with good link up play but is most lethal inside the six yard box, which we’ve missed for a long time.
“It will take him a while to settle in, with new teammates but he looks physically capable of succeeding.”
Arsenal have also signed Bosnian defender Sead Kolasinac in a free transfer from Bundesliga side Schalke 04 in June.
The Gunners won the FA Cup for the third time in four seasons in May thanks to a 2-1 win against Premier League champions Chelsea.
