Manchester City followed the signing of Adam Johnson by signing Pablo Zabaleta a new contract Friday, as the English Premier League leaders continue to lock up their players.

England winger Johnson had agreed a new deal which keeps him at the club until 2016, and Argentina defender Zabaleta signed a contract through 2015.

Zabaleta's previous contract was set to expire next season, but the versatile 26-year-old, who can plays on both sides of defense, will remain with City.

"I'm in a very good team, and I try to do my best for the club, the team and the fans," Zabaleta said. "I didn't think twice, I gave a quick answer because I was so happy to sign."

Johnson's contract, first announced Wednesday, should stop speculation about the 24-year-old's future.

"I wouldn't have signed if I didn't see a big future here," Johnson said. "I'm delighted to sign, I'm just glad it's all sorted out. It was never on my mind when I was playing. You can't let that happen, contracts can take a long time these days.

"This club's going places and I want to be up there with them at one of the top clubs in Europe. I want to become a top player, I want to keep winning things and picking up medals."
