Ireland international Paul McShane says he's been left "exhausted and frustrated" by the squad rotation policy at Hull City which saw him axed from the matchday squad last week.
And the 28-year-old says he will have to assess his options and possibly seek a move away from the club when the transfer window opens in January.
The Wicklow native started for Hull in their Premier League games against Southampton and Burnley earlier this month, before the international break, but didn't even make the bench for last Sunday's meeting with Tottenham and McShane is not expecting to feature against his former club Manchester United tomorrow.
"It's a season that's full of frustration and you can probably understand why. Sunday was a massive disappointment, especially not to be in the squad at all," says McShane, who joined Hull in 2009 from Sunderland.
"What can you say? I feel as though I'm playing well, probably the best football of my career when I'm playing centre-back.
"It's very tough to take. I'm upbeat now but it's a killer at the time You have to keep picking yourself up but how many times can you keep doing it? I'll keep doing it, even if I have to for the rest of my life but sometimes it gets exhausting," added the Ireland defender.
McShane's contract runs out at the end of this season and while Hull boss Steve Bruce has said that he's keen to speak to McShane and Stephen Quinn - also out of contract in the summer - about a new deal, McShane is unsure and may need to look outside of Hull.
"It was good to hear and it was promising but when this happens after happening a few weeks before, there's only so promising it can be," he says of Bruce's recent promise to open talks on a new contract.
"I can't stick around to be playing games, and playing well, and then be totally left out of a squad, because it is disheartening.
"I'm not sure what will happen. Probably in January when it all kicks off again I might know more but that's the life of a footballer, you don't know where you'll be from one minute to the next."
McShane is one of the longest-serving players at the club as this is his seventh season with Hull, though he has had loan spells at Crystal Palace and Barnsley while he was on the books with the Tigers and this season has been a struggle.
But the current campaign has been tough for McShane's compatriots at the club. Hull have played 12 Premier League games but McShane, Robbie Brady and Stephen Quinn have each started only four games while David Meyler has yet to start a Premier League match
Brady has come into the City side in the last two games and the Dubliner hopes to feature against his old club at Old Trafford tomorrow - Brady joined Hull from Manchester United in a £2million deal last year,.
"I can't wait. I missed the last two games against them when I didn't get chance to play so I'm really excited about it," he says of a United return.
"It'll be great to go back there for the first time and hopefully we can get a result to make it all the better," added Brady, whose recent form for Hull has been praised by boss Bruce.
