"I've loved every minute of it," Eagles told the club's official site.
"To come and play first-team football has been good for me - I feel I've learned a lot about myself and the game which can only be good for my development. I'd definitely think about coming back, but if I've got a chance to be involved in the Man Utd first team, I think anyone would take that up. If the boss comes to me and says I need another loan spell out and Watford want me, then we'll see what happens."
"I've made a lot of new friends down here - I knew some of the lads from my time here before but I know some of the older lads better now, like Neil Cox and Sean Dyche. Their experience has rubbed off on me and hopefully will help me to improve my game."
