Chelsea will be without the suspended Ashley Cole and injured Ricardo Carvalho in Barcelona.
Portugal right-back Jose Bosingwa is likely to cover for Cole at left-back, while Alex is expected to continue with John Terry in central defence.
Barcelona have no injury worries, with Henry set to return to the starting line-up having come off the bench in Saturday's 2-2 draw at Valencia.
Andres Iniesta will revert to central midfield alongside Xavi.
