With over 200 career appearances to his name already, the Scottish defender already has plenty of experience at the age of 26 and is looking forward to a new challenge south of the border.
Cox told iFollow Iron: "He's an attacking full-back who gets up and down the pitch, and that's what we want. Ross is a great crosser of the ball and creates chances. He wanted to come here from six weeks ago. We just had one or two things we had to sort out, which we've managed to do. We're over the moon that he's in the building now.
"He's 26 and has a lot of experience already, but is ready for a fresh challenge here. He's a big lad and can get up and down. He has great ability on the ball and can score goals, while wants to go up for set-plays and can defend them too.
"He's a player we wanted in for a while now since we first found out he was available. We've done a lot of work to get him here and it's great to get it over the line. He's been doing a lot of training work on his own (so far this pre-season), and now we've got him signed we can get him training this afternoon and through one or two of the tough sessions today.
"He knows one or two of the boys already, has looked around and found himself somewhere to live already, which is excellent and will help him settle in quicker. Ultimately, he just wants to train and is raring to go."
Speaking about the prospect of further additions, Cox added: "We are close, and are making sure we get the right people in. We've brought three in so far and it's about doing the right thing for this football club and getting the right characters.
"We are trying to push another one, but it has to be right. We must make sure we get the right person who is 100% committed to come to this football club, and if they're not we won't be signing them."
Finally, Cox spoke about how the first few days of pre-season have gone, saying: "The first few days have been excellent. The boys have worked really hard, we've put them through their paces and they've found it really, really tough, which is what we want really.
"The first game comes on Saturday (a friendly away at Barton Town) and we will only give them 45 minutes each but the key is to get everyone fit, sharp and ready to go."
