Dan Fitch is expecting Barcelona to make it a painful night for Sporting Lisbon on Tuesday.
"Sporting will no doubt be competitive, yet will surely present opportunities as they chase the win they need."
Barcelona [1.46] v Sporting Lisbon [8.0]; The Draw [5.1]
Live on BT Sport Extra
Unbeaten Barca drawing too often
Barcelona remain unbeaten this season, but there are signs of fallibility in a team that have now drawn four of their last seven games.
At the weekend they drew 2-2 at home against Celta Vigo. With second placed Valencia losing, Barca increased their lead at the top of the table, but Atletico Madrid are getting closer.
They have already won Group D in the Champions League, yet Ernesto Valverde has reason to be concerned about his team's struggles to score away from home. In three away matches in the competition, Barcelona have only scored once and that was an own goal against Sporting in the reverse fixture.
Sporting still have a chance of making the last-16 but to do so they must win at the Nou Camp and hope that Juventus fail to claim a victory away at Olympiakos. The Portuguese giants come into this fixture having won their last four games.
Understrength Barca prospect raises odds
Barcelona are the [1.46] favourites, with the draw at [5.1] and Sporting Lisbon out at [8.0].
The home side are a bigger price than you would find them at most weeks, with the possibility of Valverde resting key players against a motivated Sporting side, forcing the odds up.
Another draw for Barca should not be discounted, with Sporting unbeaten in eight. Another possibility is the draw half-time/Barcelona full-time double result at [4.6], as Sporting will no doubt be competitive, yet will surely present opportunities as they chase the win they need.
