Oh FFS not this argument again.
Bottom line is that we have about striker who averages about 14-15 league goals and nothing else and no other recognized forward.
If a Suarez/Lewandowski/Aguero isn't available then go for a HIguain.
If a Higuain isn't available go for Lacazette or whoever.
Because there are practically zillions of other options then playing Walcott or whoever else upfront which is the alternative.
If a club like Palace or WEst Ham can bid 35-40m for a forward and Liverpool can pony up that much for Mane then that's not big money in todays market anymore.
