Wolves sporting director Matt Hobbs said: We've never seen Tommy as a player on loan, and he hasn't acted like one. He's gradually earned more minutes and become more important, which I think is an ideal first year. What he offers to our midfield is something different to the others, so there was a huge amount of inevitability to this.
He buys into who we are as a club and what we're trying to create culturally within the group. He's a great player to have for what we're trying to achieve off the pitch and he gives us so much on the pitch, so he's the exact type of player I think Wolves should be signing.
If you look at the type of players we like to sign as a football club, they generally haven't reached their ceiling yet and have loads more to come. Tommy is a fraction of the player he will become, with the more he gets used to the league and the greater his understanding gets. I'm really excited for now but also his future at Wolves."
Doyle also stated: It's amazing. I'm really happy. I found out not too long ago what's going to happen and it's obviously very exciting for me, having enjoyed this season so far, and I'm looking forward to trying to better what we've done next season.
I've known for a little while that there were talks, and the other day it was more official. I've enjoyed it here, everyone's been really great with me, the manager, the staff and especially the lads. It'll be good to battle in the league again with them next season.
They're a great set of lads. It's a very driven group of lads who want to achieve, lads who want to push each other to become better. There's a lot of things individually and as a team I want to do next season, and this is the best place of me."
