Leicester City should consider a move for the French striker.
Leicester have plenty of centre-forward options, but it will be a real concern for Claude Puel that all of them apart from Jamie Vardy have not proven themselves to be good enough for the Premier League.
One player in particular who faces an uncertain future at the King Power Stadium is Islam Slimani, and Puel will surely be looking to bring in a high quality target man type hitman this summer, as a potential replacement for the Algerian, should he leave the club.
Standing at 6ft 3in tall, the 24-year-old is extremely strong in the air, but his game is based around so much more than just his physical prowess.
Haller has scored 72 goals in 191 career appearances - a decent return for someone so young, and his playing style would perfectly compliment the skill-set of Jamie Vardy at Leicester.
The England international thrives on knock downs in and around the penalty area, and his willingness to run in behind the opposition's defence into the channels would be the ideal foil for Haller.
The former France under-21 international likes to drop deep, and link up play between the midfield and the attack - something that makes him perfectly suited to Leicester's direct playing style.
Haller would act as a great focal point from which the Foxes could build their attacks, and he would undoubtedly offer them a different option in the final third.
According to a report from 90 min, the striker could be available for €30 million (£26.5 million), and in today's day and age, that would represent decent value for the east Midlands outfit.
If Leicester do manage to bring the Frenchman to the King Power Stadium, it would see them buck their recent trend of bringing older, more ready-made players into the club, and it could turn out to be one seriously good addition for the future.
