Chelsea boss Roberto di Matteo says Romelu Lukaku is giving him food for thought on their US tour.

Lukaku struck twice in victory over the Seattle Sounders this week.

"It's interesting to see him playing with the team," Di Matteo said. "We've had a talk at the start of pre-season and I'm very keen to see him perform for us, then we will see what's going to happen. He is a danger and scores goals. That's what a striker has to do in the team.

"We still have Fernando and Sturridge to come back but we have options and we can't forget he is a young boy but I have been pleased and he is an interesting player for us."
