Depends.
You look at players like Hoijlund, Antony, Sesko, all bought for over £70m each (and various others over the years), based on their performances in other European leagues and think, hmm, really?
I'm not saying it can't work, as equally there have been dozens of others who have come in and set the PL alight. I'm just saying it IS a gamble if you are looking at say £60m+ for your main striker option.
The likes of Chelsea can take that gamble easier than we can.
So then it's about having a good enough (and wide enough) scouting network to find the ones who are half that price. We don't appear to have that network.
We've all said it, the club needs to really enhance/overhaul the scouting to avoid this in future years.
In the meantime, if you do need to pay £60m+ for an experienced striker, do you go for one with PL experience?
