The day after Fabregas finally returned to Barcelona, the Welshman put in an assured performance in the Arsenal midfield, setting up the only goal of the game for Theo Walcott as they beat Udinese 1-0 in the first leg of their Champions League play-off.
Asked how the week has been for the players, Ramsey told Sky Sports: 'It's time to move on. He was a great player for the club but now he's gone.

Walcott missed chances to pad Arsenal's lead - including one, set up by Ramsey, which brought a brilliant save from Udinese keeper Samir Handanovic.
Walcott admitted he could have scored more, but added: 'I'm still coming back from my ankle injury. The goalkeeper's made an absolutely fantastic save. It's early days, it's my first 90 minutes, and I'm very happy with the result. That's the important thing.

'We tended to drop off a bit and there were gaps appearing but we dug in and gave absolutely everything,' he said.
'We believe we're capable of going over there to win. The most important thing is a clean sheet. Our defence was solid, like at the weekend. I believe we can get the result.'
