Hotspur play well this season as a result of a deeper bench, getting a seven-match unbeaten run despite a two-fronted attack on European games and PL games.
Sporting are less experienced than Hotspur in European games. But they can not be ignored because they got a 0-3 away win from Frankfurt in the last European games. When they last met in 2010, they were tied.
Considering that they have both scored two goals on average of the most recent games, I think the total goals of the upcoming game will be over 2.5 and the victory is tending to the guest team.
Tottenham Hotspur @1.95
Over 2.5 @1.92
