Arsene Wenger believes Arsenal timed their signing of Alexandre Lacazette well, labelling the reported €53 million paid for the forward as a "very decent" price.
The 26-year-old joined for a club-record fee, but Wenger feels that the price would have been far greater had the deal taken place later in the window.
"It depends sometimes on the timing. The inflation sometimes is so quick within the transfer market that the timing of your buys is very important," Wenger said ahead of his side's trip to Liverpool on Sunday.
"We were already on the case last year, so when I came back in I knew the player.
"Considering the market now, I think it is a very decent price. The price would certainly be very different today."
Lacazette managed double figures in league goals in his final four seasons at Lyon, including netting 28 in 2016-17.
Wenger said it would take time for the French striker to find his best form in the Premier League, but he is certain the 11-time international will deliver.
"He is still in an adaptation period to the team and to the league," he said.
"He is a bit surprised by the intensity of it all in training and in the games. He will get there because he is brave and he is intelligent.
"The intelligence of his runs and the quality of his technique is very good. Overall I don't worry for him. He is just in the [early] phase... at the start he was completely taken by the intensity of it and he slowly adapts.
"I feel every week he is getting better and stronger."/
