Manchester United defender Michael Keane has revealed he was incredibly frustrated at Derby County.
The Red Devils starlet failed to hold down a regular first-team spot at the Championship outfit due to the form of Richard Keogh and Jake Buxton.
Keane was limited to just five starts during his two-month spell at Pride Park.
The 21-year-old centre-back has since returned to parent side Manchester United and has vented his frustration at his spell under Steve McClaren at Derby.
Keane, speaking to MUTV, said on his brief spell at Derby: “I enjoyed it at Derby. It was a good experience to get out and get some games.
“We had big matches, like playing Chelsea in the FA Cup, but it was frustrating to be sat on the bench so I decided it was best to get back to United.”
Keane, whose twin brother Will is currently on loan at Queens Park Rangers, has admitted he may seal a move back to the Championship in the next couple of weeks if he cannot break into Manchester United's first team.
“All I can do is train in front of the manager every day and show what I can do,” added Keane.
“I need to keep playing and go in every day to impress him. Hopefully, I can get my chance.
“The loan window is open again but I’ll give it a few weeks at least and then reassess it.”
Keane, who spent the majority of last season's campaign on loan at Leicester City, will have to leapfrog the likes of Nemanja Vidic, Jonny Evans and Chris Smalling in the pecking order if he is going to hold down a spot in Manchester United's starting line-up.
