Lennon wants no Barcelona talk as Celtic prepare for Dundee United
The Bhoys, who tested the Catalan giants in their 2-1 loss at the Nou Camp last week, play host to Tito Vilanova's star-studded side on Wednesday night needing at least a point to stay in the hunt for a top-two Group G finish.
But the Glasgow club first has to navigate a domestic fixture this weekend when the league leaders head to Dundee United and Lennon is more focused on that at this stage.
"Before last night's game I said to the players that last week they were well motivated, in a nice climate, going out at the Nou Camp.
"It was different (against St Johnstone), maybe 15,000 to 20,000 people there, but I said their attitude had to be the same and I got that."
