Dundee boss Barry Smith believes he still needs to add more experience to his squad despite gaining a point against Kilmarnock on the opening day of the SPL season.
The Dark Blues have brought in seven players this summer and held the Ayrshire side to a 0-0 draw at Rugby Park.
However Smith fears his team may suffer from a lack of consistency unless he is able to bring in older heads.
He said: "If you look at my bench I had four Under-21s and one on the pitch.
"These boys haven't really played in the First Division so to throw them into the SPL is a massive ask.
"We think they are capable but we are looking for guys who can play at that level.
"We are always looking and hopefully in the next couple of days we will get a couple more in but that's not guaranteed."
Both sides were forced to settle for a share of the points, a result which left Smith content after seven years away from the top flight.
He said: "Kilmarnock is a difficult place to come to so we are happy to go away with a point.
"We would have taken a point before the game so we are happy.
"The overall performance was credit to the team, the way they worked and how hard they worked.
"The crowd also spurred them on and were fantastic. To bring a crowd like that is incredible and it's brilliant to see them get a boost from being in the SPL.
"The difference between the First Division and the SPL is consistency. We need that level of performance every week.
"I hope we can do it. That's why we've brought these players here because we believe we can."
