<text>  Romelu Lukaku can score the goals to keep Everton in the Premier League, according to manager Roberto Martinez. The Belgium international impressed while on loan from Chelsea last season, but struggled initially after making the move permanent last July. A total of seven goals before Christmas was fewer than Everton might have expected from a striker they had just spent a club-record 28m on. Romelu Lukaku has been phenomenal in 2015, according to Everton manager Roberto Martinez . Lukaku has struggled at times this season after his 28million move from Chelsea in the summer . But the 21-year-old has scored 11 times since the turn of the year, finding the net in each of Evertons last three matches. Martinez puts that recovery down to the fact that Lukaku is no longer suffering the after-effects of helping Belgium reach the quarter-finals of last summers World Cup. Everton are far from safe in the Premier League as they prepare for Sundays trip to relegation-threatened QPR. But Martinez feels that the goals of Lukaku will see them out of trouble. He said: He said: We made a big investment in him because we always felt that hes a one-off. Its always tough for players after a World Cup, and Rom found it extremely difficult. But Ive been so impressed by the manner in which hes put everything together. I think hes been phenomenal. His performances from January have been impressive. Now the target is to see that in the next 10 weeks, and make sure he finishes the season really strongly. Roms becoming the type of player who needs one chance to make the difference. He likes to carry that responsibility, which is something that goes with your character. Hes the full package. The Belgian striker competes with Moussa Sissoko during Evertons win against Newcastle last week . Martinez has no doubt that Everton are in a relegation fight. Last Sundays 3-0 home victory over Newcastle was only the second time his side had won in 12 Premier League matches. He said: Any team who havent got 40 points in the final third of the season are fighting for every point. Make no mistake about it. Its a massive period of the season for us. Every point is going to be extra significant for the team. Robert Martinez insists Everton are in a relegation dog fight this season .
