Anyone who believes footballers are not affected by uncertainty surrounding their club are guilty of wishful thinking.
Take it from me, if you don't know if a manager is going to be there beyond the end of a season, it will affect you. And no matter what anyone says to the contrary, that's what is happening at Rangers at the moment.
You're always going to play your best football when you're settled at home, your family are good, you're in a good place with your football, you are fit and have a reliable manager.
Graeme Murty is feeling the pressure as uncertainty grows around his position at RangersiPhone transfer software
The more settled a player is in his day job and at home, the easier it is to play football to the very best of your ability.
At the minute, Rangers players don't have that.
There are too many things not in order which probably explains the team's inconsistency.
They've lost seven games at Ibrox. They've lost to the likes of Hamilton, never mind Celtic and Hibs twice.
It's been poor largely because they've not got a permanent manager and not enough permanent players.
Too many of those doing well for them at the moment are loans. Others are out of contract in the summer and, in Lee Wallace's case, some have still to come back from injury. But, fundamentally, no one knows what's happening with the manager next season.

If people outside the club are talking about it, those in the dressing room will be, too.
Players performing well at the moment - Declan John, Daniel Candeias and Josh Windass - are probably hoping Murty stays. But if he's not committed they'll be wondering where their future lies.
Murty was thrown in at the deep end. I'm not sure a single ounce of him ever believed he was going to get the job on a permanent basis.
He was given it because there was nobody else. The fact he did well in a number of games took the focus off the fact Rangers are always looking for another manager.
You can just tell he's not the right man. As soon as it went a little bit sour against Celtic, Kilmarnock and Motherwell, a huge number of questions have been asked.
But where do they go from here? They are back where they were in December before they gave the job to him until the end of the season.
If a new manager were to come in now, that would put an awful amount of pressure on him to end the season on a high. So I don't think that will happen.
If he goes into a pre-season, you'd like to think by the end of it he'd have established a relationship with the players, got rid of the dead wood, brought in new signings and tried to build the squad for a title challenge. That in itself will probably take six months.
The Rangers players are undoubtedly being affected by the issues surrounding Murty's job
They need a manager who's going to make the same kind of impact as Brendan Rodgers. And £10-£15million of investment just to compete with Celtic - never mind win the title.
It needs to be a strong, high-profile manager. One who makes Rodgers, Derek McInnes and Neil Lennon realise Rangers are going to be a different prospect from now on.
The fact is, I don't think they have the resources or money to bring in a high-profile manager, pay him what he wants and invest in the squad to the extent they are going need to compete. I think they can only do one or the other.
Up until this point they've done neither, bringing in mostly loan players to convince people they are getting closer.
But if you lose, say, Jamie Murphy, Sean Goss, Russell Martin and Jason Cummings, you are back to square one.
The season is in danger of unravelling quickly. If they don't finish second, that will be an absolute disaster.
Their only saving grace is they've beaten Aberdeen already this season, but they don't have the consistency to suggest they can win almost every game between now and the end of the season.
