You are hoping to tap into Gray’s potential like we did with Arteta and Pienaar. It’s unlikely he will turn into a good player in 12 months. However he might show signs of progress and you take him up the option. If he finally lives up to his potential in his last year he’s then a free agent and can walk out. I’d rather give him a extra year on 30k or whatever it is then lose him if it worked out. What’s £1.5m a year to a Premier League club1 year deals are quite common in football though.
Many experienced players sign 1 year deals and many players looking for an opportunity will sign a 1 year deal with a club option for a 2nd.
Just not at Everton.
