Arteta on squad fitness, adapting to travel delays and Sunderland

Arsenal boss Mikel Arteta has been speaking to the media before Saturday's Premier League game against Sunderland at the Stadium of Light (kick-off 20:00 BST). Here are the key lines from his news conference: Defender Ben White is "fine" to play against Sunderland, despite coming off late on in Wednesday's 1-0 win over Napoli, while Jurrien Timber has been "training with us for a few days and looks in good shape". Cristhian Mosquera is "doing really well" and may be available for "either this one or the next one". Arteta praised Kai Havertz's form and said: "Kai is extremely intelligent, that's his biggest quality. He is five seconds ahead of the game and he just makes the people around him better. He is scoring goals, producing chances, his work-rate is outstanding and he is in an outstanding emotional state." He was asked about how he coped with a plane delay when going to Italy, with Arteta saying he "loves those challenges" and that the club try to act out potential problems. He added: "I try to create them in pre-season and arrive at different times so when they happen we have already experienced it. You can miss a flight and the train can be delayed, but I don't want the players or staff to be panicking when it happens and instead adapt to it. But do not complain and use it as an excuse because it's not helpful at all." He added: "We delay the meals, delay the transport, take a different route, make the dressing room hot, less beds, because we are going to have to adapt so there is not an element of surprise on matchday. It's important." On Saturday's opponents Sunderland, he said: "We experienced last season how difficult it will be and it's great to play these type of games. We have prepared, we are ready tomorrow to be on the pitch and compete like we always do - and be better than the opponent and try to win the game. Last year, we dropped points there in the last minute [drawing 2-2] and we've learned a lot from that game."
