"I think Johnson is an excellent player," Jones told Liverpoolfc.tv. "We're getting a good defender and someone who loves to go forward too, which is something I think Liverpool have perhaps been missing.
"Johnson is strong in most areas; he's good at going forward, has good pace, is strong and his defending has really come in the last couple of years.
"He's the all-round right-back and will strengthen the team. It's obvious Rafa rates him very highly."
