Sunderland boss Martin O'Neill is backing winger Adam Johnson to be a big hit for the Black Cats after his arrival from Manchester City.
The England international last night signed a four-year contract after the two clubs agreed an undisclosed fee.
O'Neill has been on the Easington-born midfielder's trail for several weeks after it became apparent that his days at the Etihad Stadium were drawing to a close, and his arrival on Wearside just hours after Wolves striker Steven Fletcher capped a good day for the Ulsterman.
A delighted O'Neill said: "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."
Johnson, 25, is a product of Middlesbrough's academy and has won 12 full England caps.
He told Sunderland's website: "It's great to have signed and it's a fresh start.
"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 missed out on a trip to Euro 2012 and will hope his latest move could help to revive his international career.
Johnson played 96 times for first club Middlesbrough, scoring 13 goals, before he moved on to City in 2010.
But after 73 games, which produced 11 goals, he has now moved to Sunderland.
He said: "I want to perform on the pitch for the fans and I'm just looking forward to getting out there now."
