Manchester City outcast Adam Johnson has signed a four-year contract with Sunderland for an undisclosed fee. The 25-year-old winger, who failed to establish himself as a first team regular at the Etihad since signing from Middlesbrough in 2010, was also a reported target for Liverpool and Spurs.

"Adding quality players to the squad has been our main aim this summer and Adam certainly fits that bill. He has terrific ability, great delivery and I'm sure he is a player who will excite our fans. I couldn't be more delighted to have him at the football club," Sunderland boss Martin O'Neill told the club's official website.

Johnson, who spent time on loan with Leeds and Watford (when contracted to Middlesbrough), said he chose the Black Cats because of what O'Neill had to say to him.

"Coming back to the north east and Martin O'Neill were the two main factors, especially the gaffer and listening to what he had to say to me. He made it clear just how much he wanted me to come here. To know that and feel wanted and appreciated made me feel that it was the right choice to sign. He knows exactly what he wants from his players and from me personally. Hopefully he'll give me plenty of confidence as well," Johnson told the club website.

Black Cats Sign Wolves Striker

Meanwhile, Sunderland also confirmed the signing of Wolverhampton striker Steven Fletcher. The 25-year-old Scottish forward transferred for an undisclosed fee and signed a four-year contract.

Wolves, who were relegated to the Championship at the end of last season, have seen key players like Matt Jarvis (to West Ham United) and Fletcher leave Molineux, with both players expressing desires to remain in the Premier League. Fletcher has reportedly been a long-time target of O'Neill's and the manager expressed his delight at the capture of the former Burnley striker, who scored 12 goals in the Premier League last season.

"It has been no secret that we needed to strengthen our attacking options and Steven has a proven track record of scoring goals. He is young and constantly improving and he will be a very welcome addition to the squad. I'm delighted that we've been able to bring him to Sunderland," the 60-year-old northern Irishman said.

The Black Cats have now signed four players so far this summer. The other two new faces at the Stadium of Light this season will be Louis Saha (on a free transfer after being released by Spurs) and Carlos Cuellar (also on a free after his Aston Villa contract expired).
