Roberto Martinez concerned about change of Agent by Romelu Lukaku

Everton manager Roberto Martinez says that he is more concerned by the fact that striker Romelu Lukaku has changed his agent midway through the season.

The Belgian international joined the club in the summer from Chelsea for a club record fee of £ 28 million, but he has struggled to have the same kind of impact that he had last time around. Everton were persuaded into spending this amount of money on the player after he had an excellent loan spell last season. Still just 21 years old, Lukaku is expected to grow into a much better player than he is currently.

However, doubts have been raised about his Everton future after he has gone for a superagent in the form of Mino Raiola, who also handles superstars like Zlatan Ibrahimovic and Mario Balotelli. This has raised speculation that Lukaku may be tempted into a move back to a big club. The striker struggled to settle at Chelsea due to the lack of regular first-team opportunities, which was cited as the main reason for moving to Everton. He has scored 18 goals in all competitions for the club, but only eight have come in the Premier League. This may be seen as a disappointing return, but Martinez is confident that Lukaku will be a great player for the club.

"He has changed his agent, yes, but we are not concerned, no. Rom is entitled to do that.Everyone speaks about the colourful character that Mino Raiola is, but he has a lot of players who are very much people who are happy to stay at one club.I dealt with Mino Raiola at Wigan and not many people know that he had Danny de Ridder or the players like Vladimir Weiss who have been happy to stay at a club,” said Martinez.
