Martin Zubimendi, Cristhian Mosquera, Hincapie and Riccardo Calafiori – three members of Arsenal’s starting defence – were all booked in the first half, along with Chelsea’s Marc Cucurella, with Arteta admitting that he felt he had to replace Calafiori as a result as he contended with the likes of Estevao and Pedro Neto.
