Chelsea lost their third pre-season friendly, 3-1 to Brighton, at the weekend.

"We haven't had the whole team together yet," Di Matteo told the club's website (www.chelseafc.com).

"Some players have only been back nine days, some 16, some 21 and some are not back at all, but when they are back we can all work together.

"I was expecting more from my team in terms of urgency and movement. I was looking for a better performance than the one we gave today (Saturday).

"We were too stretched, never aggressive enough and didn't get the ball back quickly enough when we lost it.

"With the ball, there wasn't enough movement and there were a lot of things we didn't do. We have to be a bit more focused and sharper."
