Liam Miller insists that he has no regrets about joining Manchester United, despite failing to make the expected impact at Old Trafford.
Liam Miller left Celtic at the end of his contract
He has made just 10 starts since his summer move and Celtic boss Martin O'Neill has questioned his choice.
But the 23-year-old said: "It was a decision I made and I made the right one. Hopefully, it will show in time.
"I knew when I signed the players United had. I knew it was going to be tough because of the quality."
The Republic of Ireland midfielder's case was not helped by an injury soon after his move.
A humiliating goalless draw against non-league minnows Exeter at Old Trafford in the third round of the FA Cup has since proven to be detrimental.
"The first few months I was enjoying it - and I'm obviously still enjoying it - because things were going well," commented Miller.
"I was getting chances in Europe, I was coming on in Premiership games and featuring in the Carling Cup.
"But then came the Exeter game and the whole team had a bad performance, including myself. It put me on the back foot and to the bottom of the rotation.
"I knew I had to pick myself up and I believe I have recently.
"I've been doing well in training, I'm feeling the benefits and I'm starting to get a look in again in the league.
"I suppose Martin is entitled to his opinion.
"When I was playing for him, I had great respect for him and he has always been great for me.
"Maybe I can understand his frustration at me leaving.
"But, with Eric Djemba-Djemba leaving, it has opened the gap a bit more for me to get in again."
