LONDON -- Arsenal manager Arsene Wenger insists he has no regrets over his decision to reject the option of bringing Cesc Fabregas back to his club this summer, but he admits it is "strange" to see him in a blue Chelsea shirt.

Fabregas impressed on his Premier League debut for Chelsea against Burnley on Monday, leading to questions about Wenger's decision to turn down the chance to re-sign him when he left Barcelona.
"I have no regret about that at all. My regret is that he left us," Wenger said about Fabregas at a news conference, before he was asked how he felt seeing his former skipper in Chelsea colours.
"It was strange, but you have to accept that professional players move from club to club," he said. "It was difficult for him to leave us, but after that you accept he can move to some different clubs. Of course it was a bit strange, but he had a good game."
Wenger went on to suggest the departure of Fabregas opened the door for the rise to prominence of Aaron Ramsey, hinting the potential of the Wales midfielder could be even greater than that of Fabregas.
"What is good in life is that someone moves out and someone else takes over and he has developed," Wenger said.
"Ramsey has a different style to Fabregas, but he has developed into a player with huge potential. There is more coming out of Ramsey. He is younger that Cesc and the potential is there to get more out of him."
Wenger again suggested that his transfer activity in the final few days of this summer window will be focused on trying to sign defensive players, with ESPN FC sources confirming Olympiakos defender Kosta Manolas is on his wanted list.
"We listen to the names [being linked with Arsenal]," Wenger said. "Sometimes I look to see who we buy in the media.
"At this moment, we are in an emergency case. We have the players we want. We are open to any opportunity in the transfer window who can strengthen our defensive department in quality and number.
"I am open to do it [sign players], but it has to be linked with the needed quality. I tell you something, 20 top clubs in the world, they look all for the same positions, so it is not necessarily out there."
He added: "A team doesn't stand still. We move forward and improve. We have young players and that means every year they can be better. A team improves as well with success, which we had reasonably last year.
"Overall we were quite consistent last year, but we have a good opportunity to show [against Everton on Saturday] that we have moved forward again.
"Your job [in the media] is always to imagine a disaster. My job is to believe in what I do and what the team does. We made 79 points last year and we want to make more this year. It is a reasonable target. I think we have a squad more equipped to do that and we have made a good start."
