Birmingham winger Daniel de Ridder admits he may have to consider his future after becoming 'frustrated' at his lack of first-team opportunities.
The Holland Under-21 international, signed on a free transfer from Celta Vigo last summer, has not featured for Alex McLeish's side since the FA Cup clash with Huddersfield in early January.
The emergence of Sebastian Larsson as a key player has contributed to De Ridder being sidelined.
But De Ridder has hit out at the perception that he is injury-prone and is baffled at his lack of first-team involvement during the past three-and-a-half months.
He said: 'When Alex McLeish came in, I played in his first game at Tottenham and we won and I thought I did well. I have watched the tape back and I was described as one of Birmingham's most dangerous players.
'Then I came on at Manchester United along with Mikael Forssell and I thought we made a difference and changed the game. But everything has altered for me 180 degrees and I am frustrated I am not involved in the squad.
'Sebastian Larsson has done very well but, although I am not the same sort of player, I believe I can still add something to the team even if it is making an impact as a substitute or on the left side.
'It is frustrating because I like the club, the city and the fans and I hope we can stay in the Premier League. But I also have to think about my own career if I am not playing.'
As regards the perception that he is injury-prone, De Ridder insisted: 'I want to make it clear I have only had two injuries since coming here.
'I got a kick on the leg in the opening game at Chelsea which kept me out for six weeks and a hamstring strain in a reserve game in early April which kept me out for 10 days.
'Apart from that, there has been nothing. I am training hard and would love to be involved - but it is the manager's decision.'
Meanwhile, midfielder Mehdi Nafti is undergoing treatment to his thigh injury in a battle to be fit for Saturday's crunch clash at Fulham.
The Tunisia international suffered the setback during the first half of the 2-2 draw with Liverpool at the weekend.
