The Magpies need to avoid the silly approach of trying to find cheap, unproven talent. Sometimes, it really doesn't work...
A year on, that forward is yet to score for the club. He's yet to even play a game.
Clearly, the Argentine wasn't fit enough to survive in the Premier League, while much was made of how disappointing Ferreyra was in training in terms of his ability.
There are no two ways about it - Newcastle tried to be clever in signing him and it backfired. As ever under Mike Ashley, the Tyneside outfit were looking for cheap, unproven talent. And Ferreyra was the perfect example of that approach seeing money simply thrown down the drain.
The same approach this summer would be Newcastle's biggest mistake in the transfer mistake. The Magpies need to avoid another Ferreyra-type signing at all costs. Yes, the same could be said for Ayoze Perez, who came good. But Perez was a proven goalscorer in Spain - a recruit well worth going for, unlike his fellow summer signing.
With the club yet to purchase anyone this time around, though, they may be pushed into a few corners this summer in the temptation to do just that. But, in Steve McClaren, United have a coach who has been around the block and knows a number of transfer targets first-hand.
Newcastle would be wise to utilise that knowledge. Enough looking for the cheap, next best thing - this is the Premier League not the X Factor.
