Torino fell to their first European defeat of the season after a disastrous second half performance saw the Granata lose 2-1 to HJK Helsinki on Thursday night.
Giampiero Ventura gave summer signings Juan Sanchez Mino and Josef Martinez rare starts, whilst Daniele Padelli also returned in goal.
Former Boca Juniors midfielder Sanchez Mino had the only chance in the first half, but his long range shot was turned onto the post by home keeper Toni Doblas.
However, on the hour mark the Finnish champions took a surprise but deserved lead when some unconvincing goalkeeping from Daniele Padelli allowed Gideon Baah to score from close range.
Ten minutes before full time the home side doubled their lead, as more hesitant Toro defending allowed Valtteri Moren to find the net. Toro almost had a glimmer of hope of rescuing a point after Fabio Quagliarella scored in the final minute of normal time, but it was too little too late from the Granata.
This result pushes Toro down to 2nd place in their Europa League group, however a victory in three weeks time at the Stadio Olimpico against leaders Club Brugge should be enough to send the Granata through.
