Andres Iniesta has responded to his critics by claiming he 'never went away' following a vintage first-half performance in Barcelona's 2-0 win over Paris Saint-Germain on Tuesday night. The Spaniard had failed to register a single assist or goal from 19 La Liga appearances this season, prompting critics to suggest the 30-year-old was on the decline.

'It was not easy at all, despite us having the 3-1 advantage. We're peaking at a great time by playing well at the end of the season. We have gone from strength to strength, which is what it should be like. 'We're in great form but we know that matches can be decided by the smallest of details. We know that our presence in the semi-finals is important, though, and it's great that we made it that far.'
