Striker Romelu Lukaku has announced he will not be officially presented at Chelsea this week, with a deal yet to be confirmed.
The Anderlecht hitman is on the brink of an £18million move to Stamford Bridge, with the two clubs having already reached an agreement.
Lukaku travelled to London to undergo a medical at the Premier League club earlier this week and was expected to be officially revealed by the Blues on Thursday after agreeing personal terms.
However, the 18-year-old has released a statement on his official website saying there has been a delay.
The statement read: "Please note that no official presentation and no press conference will take place in Chelsea this week.
"More news will be given on the site in the coming days."
Lukaku travelled with the Belgium squad to Slovenia on Tuesday night for a friendly match, which ended in a goalless draw.
