The Swedish centre-back currently plays for Copenhagen – the Bianconeri’s Champions League opponents tomorrow.
And the veteran has admitted that the Old Lady have changed radically since he departed in 2009.
“The team has changed a great deal since I was there,” he said.
“Back then they had plenty of experienced players, such as Del Piero, Trezeguet, Camoranesi and Nedved. Now they’re a younger group and have changed their style of play.
“Only Buffon, Chiellini, Marchisio, Giovinco and De Ceglie have remained from my spell in Turin. It’s a completely different side and I think they’ve improved.”
“It will be difficult because we haven’t had much time on the training ground to prepare specifically for this clash. But we’ll give it our best shot and try and get a result.
“We’re aware of the dangers that we could potentially come up against, I played against Carlos Tevez when he was at Manchester United and tomorrow will be a tough battle against a striker of his quality.”
