Inter head coach Simone Inzaghi tried to look on the bright side after his team were beaten 4-2 by Villarreal in their final pre-season outing before the new Serie A campaign.
The contest in Pescara on Saturday saw Romelu Lukaku find the net for the second time since returning to the Nerazzurri on loan from Chelsea, while Danilo D'Ambrosio also scored.
However, goals for the Yellow Submarine from Alfonso Pedraza (two), Francis Coquelin and Nicolas Jackson gave Unai Emery's side an impressive win over the Italian giants.
Speaking after the game, Inzaghi simply said: "These tests help to grow, and there are things to review, but we played against a team that last year reached the Champions League semi-final."
Since beating FC Lugano 4-1 in their first pre-season outing, Inter have not won any of their four subsequent friendlies, drawing with Monaco and Lyon and losing to Lens and Villarreal.
Dutch centre-back Stefan de Vrij was more direct in his words, saying post-game: "Too many goals conceded. We have to keep working, because that's not enough."
Inter begin their Serie A campaign away to Lecce on August 13, as they look to reclaim the Scudetto after losing out to local rivals Milan last season.
