In today's transfer market, £45m is simply the going rate for any new striker coming into the Premier League from across Europe.
Almost £100m has already been spent by top-flight clubs on centre-forwards this summer, but the arrival of Eintracht Frankfurt's Sébastien Haller ahead of the 2019/20 campaign will be among the most high-profile new signings in the Premier League next season.
Just like with any player moving to England from across Europe for the first time in their career, an air of mystery is understandably going follow - especially for stars who are tasked with scoring the lion's share of a team's goals that season.
