Manchester City trained at Napoli's Stadio San Paolo on Thursday as Pep Guardiola's men returned to the scene of their 4-2 Champions League win from the night before.
Away sides are often granted permission to train at their host's stadium before European fixtures, but it is slightly unusual for them to use their facilities afterwards.
Guardiola decided that staying in Italy and having a light session there before heading back to England later on Thursday would be the best way for his team to prepare for Sunday's Premier League clash with Arsenal.
