text: Everton manager Roberto Martinez insists he is not worried that Romelu Lukaku’s new agent will destabilise the player — even though incendiary comments last week look like they were made with that intention. Lukaku was absent injured as Phil Jagielka’s goal settled this match to give Everton a third straight victory. But the win came in the wake of Lukaku’s new agent Mino Raiola saying Lukaku would never have signed for Everton had he been his representative earlier. ‘Later on, he’ll play for one of world’s best teams: PSG, Manchester City, Manchester United or Bayern Munich,’ Raiola said, sparking uncertainty over the future of the 21-year-old Belgian, who became Everton’s record signing when moving from Chelsea for £28million last summer. Romelu Lukaku (left) has had some big claims made about him by his new agent Mino Raiola (right) Roberto Martinez has dismissed claims suggesting his star striker could leave Goodison Park . Southampton have scored just five goals in nine games since the start of February (0.55 per game). This is less than a third the rate before that (1.68 per game). ‘In the modern game you don’t get the values of 25 years ago,’ said Martinez, implying a decline in standards of behaviour by agents. ‘But when you have a player on a long-term contract there is nothing to discuss. That is straightforward and clear.’ Lukaku signed a five-year contract at Goodison so will have four years remaining after this summer. ‘My focus is that Rom keeps on developing,’ Martinez said. ‘Without a doubt we have been the best club for him because he has had his two best seasons that he has had as a professional and we love Romelu. Agent Raiola said he would have never sanctioned Lukaku’s £28million move to Goodison Park . Raiola hinted that Everton are just a stepping stone for Lukaku on his route to the very top . ‘It has been a joy to see him developing, there is going to be a lot of talk when you score goals as a striker, you are going to get the attraction of other teams … If an agent is going to make those comments, then it is normal that you are going to ask about it. An agent can say whatever they want and it is down to everyone else to see what is behind it.’ Martinez’s counterpart, Ronald Koeman, admitted Saints’s chances of Champions League football next season were all but extinguished by this defeat. ‘It’s not realistic [now] to finish in the top four,’ he said.’
