Hearts have completed the signing of Nigeria international Juwon Oshaniwa.
Former Reading and Ipswich striker Noel Hunt has joined Southend United on a one-year deal.
Sergio Aguero has rejected speculation linking him with a move back to Spain and says he is happy with life at Manchester City.
Former Atletico Madrid ace Aguero has been linked with a possible big-money move to Real Madrid with the Spanish giants reported to be keen to lure the striker back to La Liga.
However, Aguero claims he is happy in England and that he feels he is improving as a player by playing in the Premier League.
"The truth is that I'm happy," Aguero is quoted as saying in the Daily Mirror. "The club treats me very well. It's very calm - it's different to being in Spain or Argentina.
"The only thing I do is enjoy football, rest, be at home and go out to walk around or eat in peace.
Aguero added: "You are always improving. English football, for example, being so fast, it allows you to develop your concentration and refine your technique.
"So every day you're learning and I feel that I still have plenty to learn. I have always said that in every match, watching or training, you learn things. It's like in any job, you know what to do or not to do.
