Lautaro Martinez’s late equaliser rescued disappointing Inter Milan a 1-1 Champions League draw against Real Sociedad at the Estadio de Anoeta.
Last year’s beaten finalists Inter had failed to have a single shot on target in their opening Group D tie when captain Martinez fired home in the 87th minute.
Brais Mendez had given Sociedad an early lead but the Spaniards, back in the Champions League for the first time since 2013-14, were cruelly punished after twice hitting the woodwork.
Inter thrashed city rivals AC Milan 5-1 on Saturday, but were a shadow of the side which have won their first four Serie A matches.
Sociedad lost 2-1 at Real Madrid on Sunday and have won only one of their first five LaLiga games, but went straight on the offensive.
Ander Barrenetxea had already hit the crossbar before Inter defender Alessandro Bastoni slipped in possession, allowing Mendez a free shot on goal, which he buried.
Marko Arnautovic headed Inter’s best chance before the break wide, but Sociedad went close to extending their lead.
Robin Le Normand’s diving header from Takefusa Kubo’s excellent cross flew inches over the bar and the impressive Kubo forced Inter goalkeeper Yann Sommer into a low save just before half-time.
Sommer made an even better save early in the second period to keep out Mikel Oyarzabal’s header as Sociedad chased another goal.
Le Normand’s header was blocked before Inter were given a reprieve in the 65th minute after referee Michael Oliver had shown Inter’s Nicolo Barella a straight red card.
The Italy midfielder appeared to stamp on goalscorer Mendez, but Oliver rescinded his decision after being asked to check the pitchside monitor by VAR.
Mikel Merino then headed another cross from Kubo against the bar for Sociedad as Inter failed to pose an attacking threat.
Simone Inzaghi’s side had mustered one attempt on goal throughout the game when they thought they had equalised.
Carlos Augusto side-footed home Alexis Sanchez’s low cross into the area in the 79th minute, but his effort was ruled out for offside.
But in the 87th minute the Italians levelled it up with their first shot on target.
Martinez raced on to Davide Frattesi’s low diagonal ball into the box and lifted a superb first-time shot over Sociedad goalkeeper Alex Remiro.
