"It's brilliant to have Gareth back," said McCarthy to evertontv. "Obviously we played a lot together last season and I really enjoyed it.
"He's an experienced head and he gives you so much. He helped me kick on last season and now he's back here full-time, which is brilliant for the Club and also each and every one of us.
"He was always there for me last season. If I got caught out of position he would cover for me and vice versa, I would try to cover him. But he'd always be talking - on and off the pitch - and it's brilliant to have such an experienced head alongside you."
