Celtic manager Neil Lennon has said he would like to add more experience to his squad.
The Northern Irishman has signed mostly younger players during his time in the Parkhead hot seat.
But, despite claiming to be happy with his players, he said he would prefer some more old heads in the squad.
"I am pretty happy with the squad at the minute. It needs tinkering a little but I would be happy to get just one or two more in," he said.
Lennon numbered Emilio Izaguirre, Beram Kayal and Gary Hooper among his signings last term, with Izaguirre the oldest, at 24.
And the Celtic boss has continued his interest in younger players this close season, with the signings of 19-year-old Welsh full-back Adam Matthews, 20-year-old Kenya international Victor Wanyama and English defender Kelvin Wilson, 25.
However, he intimated that he was looking for some older heads to join his side.
"We have to be a little bit more imaginative in where we go and exploit different markets," he added.
"Last season, we brought in Beram Kayal, Emilio Izaguirre and Gary Hooper - players who were under the radar who we felt would enhance us as a team, and have done.
"And we have done the same this season. We have brought in Victor Wanyama and we feel we have found a really good player as well.
"But we don't always want to go down the youth route. We are looking to bring maybe one or two experienced players as well into the squad."
