Arsenal midfielder Tomas Rosicky believes the Gunners are to be more disciplined on the pitch as red cards in their first two Premier League games have cost them vital points.

Speaking to Arsenal Player ahead of Sunday’s massive game at Old Trafford against Manchester United, the Czech International was delighted for Wednesday’s win in the Champions League, a game in which he came on as a second half substituted and enjoyed a fantastic game as he helped the Gunners in achieving their comeback.

On the departure of Cesc Fabregas and Samir Nasri, the midfielder declared that it is always difficult when key players leave the Club as he confessed he was also sad to see the Spaniard leave as the two are very close friends.

On drawing Borussia Dortmund in Group F of the Champions League, the 30-year old was full of praise for his old Club as he admitted that it will be a nice experience to feature again at the Signal Iduna Park, the former Westfalenstadion when he was in action.

And on Sunday’s game, Rosicky concluded by saying that what will be vital is to enjoy a good start and to of course finish the game with eleven men as red cards or suspensions suffered so far have indeed cost the Gunners important points in the table.

Ahead of the Manchester game, he said:

[Our season start?] Obviously you have to split it up a little bit because of course we made a very important step in the Champions League, which was massive for us [but] on the other side we didn’t start well in the Premier League so we have to improve there.

In this moment it was vital we go through against Udinese and to be in the Champions League again, it gives us confidence as well because in our first two Premier League games we didn’t win a single game so I think we will now go to Manchester and fight very hard.

You hear what is going on and when players are leaving that’s always uncomfortable but we’re here to play football not to get distracted by rumours even when someone trusts you or didn’t trust you, you will go out and you will try your best to win the games.

[Udinese?] Of course I’m very happy that I helped the team to get through, I came when we were one nil down and we were able to score the goals we needed, it was great, I would like to have influence like this, of course.

[Cesc Fabregas?] Yes, obviously it’s a massive loss for us because first of all Cesc was a great football player, his vision was remarkable and for me, I lost a very good friend, because we were very close so it’s a bit sad but yeah, as you said, that’s football, players coming and going, no players bigger than the Club but obviously I would have wanted him to stay there.

[Borussia Dortmund in the group stage?] I spent six years there so obviously I have a feeling for that club as well because I was successful there so I’m happy that they are in the Champions League again because the whole club was in big trouble so I’m very happy that they are back on track.

I think it was the most difficult team that we could get from Pot 4 so from a football point of view I didn’t want to go there but on the other side, for the private side, I’m happy to play there again because as I said I spent six years there and had a good time.

[Manchester United] We have to be disciplined from the start as in the first two Premier League games we had suspensions, it’s costing us points and also to be compact, it’s vital to stay with eleven [men].
