Arsenal have entered the race to sign Inter Milan striker Lautaro Martinez this summer, but Mikel Arteta has been given a worrying reminder after previous transfer mistakes at the club.
Until recently, Arsenal have never been a club that throws large sums of money at new signings, but they broke their philosophy to fit with the modern game. Since 2017, a combined £170million has been spent on Alexandre Lacazette, Pierre-Emerick Aubameyang and Nicolas Pepe.
It's fair to say that they haven't received the expected return on investment, as they only have an FA Cup to show for it. And this is why Arteta should be cautious before splashing out on Martinez in the summer.
