Arsenal are up and running again. The question now, and it is one at the forefront of Mikel Arteta's mind, is over how much further those players can go and at what speed.
If there was one pertinent observation from their home win over Manchester United on Wednesday, aside from the lifting of the murderous mood at the Emirates Stadium, it was the marvellous fury of Arsenal's movement in the first half and the quite sudden way in which that intensity dropped in the second.
A pattern had already been established when they faded to defeat from a winning position against Chelsea on Sunday, so it is for good reason that Arteta is resisting some of the excitement that has spread following his first victory at the third attempt.
