Nottingham Forest manager Martin O'Neill said it is a fine balance between going for the points up for grabs and experimenting with his line-up for the visit of Blackburn tomorrow.
The Reds welcome Rovers to The City Ground with the a top-six finish looking like a big ask and O'Neill said it is something that needs to be balanced.
He said: "We have a number of points to play for still, so there was an element of experimentation the other night. But in the last couple of weeks, I mentioned before that I wanted Arvin to be involved with us. He came on as a sub against Rotherham and started the game the other night so that he at least has a taste of it and will obviously want more.
"There are a few lads in the Under 23s who have shown a great attitude. Of course, we are still playing for points and it would be a shame to talk about total and utter experimentation and then find out that five victories could have got you there.
"I think the games would have to run down before total experimentation could take place; it is about finding that balance."
Blackburn arrive on Trentside fresh from a midweek victory over Derby County and O'Neill knows it will be a tough task against Tony Mowbray's side.
He said: "Blackburn Rovers, if the game the other evening is anything to go by, showed a really good will against Derby and they played very strongly.
"I have got to a stage now that there may have been, in the past couple of seasons, there may have been games you would have earmarked and think that you are at home, you are very strong and that you can win. I haven't seen that yet and for us, particularly in our type of development at the minute, I have found all of the matches, both home and away, pretty difficult."
