Alfa Romeo team principal Fred Vasseur has admitted the team failed to show its full potential throughout the Spanish Grand Prix weekend.
The team slumped in form with Kimi Raikkonen and Antonio Giovinazzi finishing just 14th and 16th place respectively, with Giovinazzi finishing ahead of the Williams pair only.
With other midfield teams around them scoring points and pushing on with developments, Vasseur admitted the weekend was simply not good enough in terms of performance.
"It was a disappointing weekend where we never managed to express our potential," he said after the race.
"It is difficult to find some positives, as the first stint of the race was just a nightmare, but at least the last stint was the best part of the weekend.
"Circumstances didn't help and with Antonio's grid position and Kimi falling to the back in the opening lap, our race was effectively compromised.
"I would say that today's result belittles our real level: everything seemed to go against us this weekend, but it's important for the two days of testing ahead that we honestly assess our performance and get back to where we stood so far this season."
