Can't say I think Havertz looks anything like Özil, it's not like he's attempting to do any of the same things. One of Havertz, Martinelli or Saka definitely should've scored in that half.
White not being at right back is definitely affecting Saka. Partey is eventually drifting into the sort of position he would normally occupy when we move forward, but White has only made one run I can recall in his usual advanced areas on the right flank.
Rice has looked very good, ambitious and crisp passing and was central to our second period of sustained pressure that half.
I have a strong feeling Arteta will just tell the players everything's going fine at half time … "there was an error but we're creating lots of chances" etcetera. He won't want to abandon today's dreams after forty-five minutes, he never has before.
