The Everton forward thinks a recent training trip to Qatar has helped the entire squad.
After being knocked out of the FA Cup by West Ham United, the Toffees had an extended period of rest before their visit to Selhurst Park, and used that time to take in a training camp.
Lukaku believes that the benefits of the trip were evident in the 1-0 over Palace on Saturday, and that playing against his defensive teammates Phil Jagielka and John Stones has paid dividends for them and him, with the forward bagging the only goal of the game.
The central defenders were also in fine form throughout the game, snuffing out Palace’s forward line and securing Everton’s second successive clean sheet in the process. Now, Lukaku has praised their performance and their effect upon his game.
“They [Jagielka and Stones] were different class,” Lukaku told evertontv.
“I trained against them the whole week when we were in Qatar. It was good to train against them because they took me onto another level and I got them to push themselves to become better.”
The Blues had been on a terrible run of form before the success in London, with just one win secured in 13 games, and the Belgian was full of praise for the travelling supporters following the victory.
Lukaku celebrated with the 2,800 travelling Evertonians at the final whistle and thanked them by throwing his shirt into the crowd as a show of gratitude.
“They were brilliant,” added the Belgian.
“They were just wonderful today and supported us through every moment. It’s good when you have support like that.”
