Everton striker Romelu Lukaku says he'll always be a Chelsea fan.

The Belgium international was happy for his old club after this season's Double triumph.

"I'll always be a fan of that club," he told SportVoetball. "Just because I left under the wrong circumstances, the feeling doesn't disappear.

"They say 'what if you hadn't gone?' But a footballer wants to play. I sent a message after the title to Eden Hazard, as I do if he scores or gives an assist.

"When they got Fábregas and Diego Costa, I thought right away: 'My God, this is going to create sparks.' One can give passes, the other finish.

"The friendly match against Vitesse, the difficult games against teams like Burnley, Chelsea played totally different than the season before. That was true champion stuff."
