The Ivory Coast international admits that he had a poor campaign last term and feels like he owes under-fire manager Alan Pardew and the Magpies' fans more in 2013-14
The 26-year-old says that he underperformed last season as the Magpies struggled in the Premier League but insists that he is eager to return to the form which helped the team to a fifth-placed finish two years ago.
Russian giants Lokomotiv Moscow have been linked with a move for the ex-FC Twente midfielder but the player himself says that he is focused on turning things around on Tyneside.

The Ivory Coast international also urged the Toon faithful to remain united behind manager Alan Pardew despite their poor results last term.
"When you do well, you are the best manager and the best players. When the team struggles, you are criticised. That's football," he observed. "The manager and the players understand this. We have to believe in him and stay together.
"I think he is a very good manager and I think next season will be different."
The midfielder is targeting a return to Europe for Newcastle next season after a run to the Europa League semi-finals last year.
"I think we can again challenge for Europe. I think it will be different to this season. It was really difficult for us," he added. "We didn't have a massive squad and we played in Europe as well as the Premier League. I think next season is going to be much better."
