We ended up with nine men for the final 31 minutes at Everton on Monday after two controversial red cards but managed to hold on for a draw.
Now we face a resurgent Rovers, back in the big time and no doubt full of confidence after a draw with champions Manchester United on Wednesday.
Glenn insisted: “We go up there with a lot of optimism and we have to be confident.
“That mental strength and show of character with nine men at Everton, if we show it with 11, there is no limit to what we can achieve.”
Glenn revealed that Monday’s heroics had taken its toll but the lads were buzzing before departing for Lancashire on Friday.
“Monday was very tiring, especially playing 30 minutes with nine men,” he said. “It’s okay to play four or five minutes and hang on but when you work so hard, the lads really felt fatigued right up until Thursday.
“Ledley, for example, today is the first day he’s been able to train with the stiffness. That just shows you, but he’s okay.”
Glenn Hoddle has called for his players to reproduce the spirit of Goodison Park on the eve of Saturday’s tricky trip to Blackburn Rovers - claiming there is 'no limit' to what we can achieve with that character in the side.
