The Catalan coach says talk of technology is "not my business" after seeing his Premier League champions concede a controversial effort at Molineux
Manchester City manager Pep Guardiola was reluctant to criticise the officials after his side's controversial 1-1 draw with Wolves.
Having survived a scare when Raul Jimenez had a goal disallowed for offside, City hit the woodwork twice in the first half through Sergio Aguero and Raheem Sterling.
But Wolves then went ahead in hugely controversial fashion 12 minutes into the second half as Willy Boly turned in Joao Moutinho's cross at the far post with his right hand.
