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 . ’
Raiola agent Mino Romelu Lukaku 's said his client would leave for big club . However Roberto Martinez is not concerned by Romelu Lukaku 's 's recent claims . Lukaku missed Everton 's 1-0 win over Southampton due to injury .
