• Arsenal's firstleg defeat to Porto puts their Champions League campaign in jeopardy.
• Thierry Henry questioned William Saliba's defensive abilities before the match.
• 'I questioned' Saliba again for not attacking the ball, according to Henry.

Arsenal will now have to do it the hard way if they want to remain in the Champions League after their firstleg defeat to Porto on Wednesday night. From start to finish, the performance from Arsenal just didn't seem right, despite scoring 11 goals in their last two Premier League games. Thierry Henry highlighted a weakness in William Saliba's game and how he sometimes doesn't attack the ball when inside the box.

Galeno had an easier chance that didn't hit back of net. Thierry mentioned questioning Saliba about this issue prior and also noticed David Raya being upset as he allowed his counterpart multiple closerange efforts on goal. There were question marks over Arsenal's number one himself regarding conceding Porto's winning goal because he should have done better.
