Newcastle boss Eddie Howe is delighted with new arrival Kieran Trippier.
The England fullback's move from Atletico Madrid was completed today.
Howe said, "We're delighted with the signing. He's a player I know very well from Burnley. He will bring a huge amount off and on the pitch.
"He has leadership qualities and a winning mentality that will help us to succeed. On the pitch we have a technical player, a level of calmness on the ball and a top defender too, so I'm delighted with the signing.
"We have not intended it to be a statement signing, we've just identified the right player for a position. It is important that I know what Kieran will bring to team. He has real experience so when you're in a relegation battle that type of player is crucial. He's up for the fight, but he sees a longer term vision for the club and his career.
"It is a sign that the club has a huge pull and I'm not talking financial. Kieran hasn't come for that, he's come for the club and the challenge and the longer-term vision.
"It is a massive thing for the club. Hopefully with his signing, other players around the world will share his dream and vision."
Asked if there are more to come Howe says he is confident but "can't give any promises on that."
He added: "We have been working for a considerable time to improve the squad. There is nothing imminent, but we will be working hard for the duration of January.
"It's changing by the hour but we will be working hard. We're in the hands of clubs selling players, we are in the hands of agents and players wanting to come. There's no guarantees. It might sound simple from the outside. It's very, very different when you're on the inside. So I'm confident but there's no promises."
