Celtic are looking for "experienced winners" to bring trophy success back to Parkhead, assistant manager Johan Mjallby has revealed.
Former Middlesbrough midfielder George Boateng, 34, this week joined the club on trial following his release by Hull as Neil Lennon looks to add to his first two signings. Lennon, who last week brought in South Korea international full-back Cha Du-Ri and Charlie Mulgrew from Aberdeen, has also spoken to Sol Campbell and Jimmy Bullard over possible moves.
"It's important to have experience in the side," Mjallby said. "We like winners at this club. Sol Campbell, he has had a great career. George Boateng has done very well, he has been down in England playing for a few clubs there and played very well."
Lennon and Mjallby led Celtic to eight consecutive Clydesdale Bank Premier League victories after taking over in March, but the club still finished six points behind Rangers and ended the season without a trophy.
And the Swede revealed mental strength was one of the main requirements as Celtic's new management team continue their recruitment drive.
He added: "It's always nice to get a couple of experienced winners in, guys who are very strong in their minds and know what they want on the pitch. That's what we are looking for.
"Even Jose Mourinho is probably looking for players in every department and so are we."
The former Celtic defender added: "When I first came here, we had a lot of good ball players in the side. We lacked a wee bit of steel. I think we lacked a wee bit of mental strength. You could see away from home we dropped too many points last season and conceded too many goals.
"If you want to be successful, you need to be able to grind out results, especially away from home. Be strong, win the battle before you can start to play good football.
"You want to win every game and you want to win in style, but you don't always get that chance."
