Roberto Mancini slammed his Inter Milan after their 2-0 defeat to Lazio.

Miroslav Klose and Antonio Candreva struck the goals for Lazio.

“In the first 20 minutes especially we were awful and deserved to lose," Mancini told Mediaset Premium and Sky Sport Italia.

“We had chances to equalise in the second half and, as usual, got them wrong. We lack quality and concentration.

“We had enormous difficulty in scoring a goal. This team lacks quality. If you watched today's game, there were many areas of the team that need fixing…

“There were slender hopes for third place, which was to win here and hope Roma slipped up. At least we wanted to secure fourth.

“Instead, our performance was in parts pitiful. The attitude was totally wrong. We were sluggish, it looked like a pre-season friendly. Many of the players have to realise Inter is Inter.

“I repeat, the season is good. We hoped for third place and considering the way the season began, we had the chance to achieve it.

“In a way, that strong start made some people think we could win the League, whereas we've got serious frailties.

“Unfortunately in these games we lack quality, we make the wrong passes and are technically poor. We keep misplacing some really easy passes. We have to work on the basics.

“It is a young team and they may well have needed this time to get settled, but from next year we have to wipe out these errors."
