I always felt that Vydra would eventually become a Premier League player, but it wasn't worth us buying him.
He clearly had some talent, and had a nack for getting crucial goals; but anyone with a brain would also agree that he was never really good enough, especially as a starter. For instance, he was very weak physically, and generally looked inexperienced which was to be expected.
Even with his fairly poor season with us, if we'd have wanted to sign him, he'd have costed around £8 million pounds as Udinese were/are in no rush to sell him, so it was either stump up the cash instantly and try and develop him, or let him go back to Watford and further develop him.
For us, it was a no-brainer. We weren't in the position to invest/gamble a large amount of money on a fairly unproven kid - but as I say I think he will be decent next season, albeit this is with another season of experience under his belt.
