Yesterday’s 3-2 loss at Inverness Caledonian Thistle means that the Bhoys are now one point behind ‘Gers after playing the same amount of matches.
With three fixtures left, Lennon says that Walter Smith’s men have the edge in the race for the Premiership which Celtic have not won in the past two seasons.
“The title is in Rangers hands," said the former Hoops midfielder. "They are a point ahead and we have to win all our games and take it to the last game of the season and see what happens.
"If teams are as committed against Rangers, as Inverness were against us, then there might be (another twist).
"Anything can happen on a given day but I didn't want this to be the given day.
"We let ourselves down, not just the players but myself, Johan (Mjallby) and Alan (Thompson) will have to take criticism.
"We might have picked the wrong team."
