The 30-year old former Celtic and Middlesbrough centre-back joined the Well as a free agent on Monday and says that a summer talk in Florida with the Fir Park boss helped motivate him to put pen to paper.
"You need to go with your gut feeling and mine told me to come here. I enjoyed my time with Hibs but the manager was a big factor in my decision," he said.
"He told me what he was trying to do this season and said he wanted me to be part of it.
"I haven't come back to Scotland just to run down my career. There's more football in me than a one-year deal.
"Anyone who knows me knows I'm quite a driven person so I want to be successful and leave a good memory for the Motherwell fans.
"It's a completely different challenge for me here.
"Growing up at Celtic, the demands are that you win leagues and cups and play in Europe every year.
"I think life will be harder for me at Motherwell, but it's something I'm really looking forward to.
"I'd be lying if I said I watched every SPL game last season but I'm aware of how Motherwell finished and I'm passionate about playing in this league."
