Jonny Evans leg injury a concern for Manchester United ahead of Newcastle trip Van Persie's two goals, his seventh in eight appearances since arriving at United from Arsenal in August, overturned Pantelis Kapetanos's 14th minute opener for the Romanian champions, which gave another example of the defensive problems that have dogged Ferguson's team so far this season. The United manager, speaking in his half-time interview on ITV, described the Cluj goal as a 'shocker, an absolute shocker," but the injury doubt over Evans now threatens to add to the defensive worries in the build-up to the weekend trip to Tyneside. With Van Persie and Wayne Rooney linking well on their first start together - Rooney made both goals for the Dutch forward - Ferguson admits that the pair are capable of forming a devastating partnership. Everyone thought it was going to be a miracle combination. But the best thing about them is they can both turn a game, and that's an important feature of them both. It doesn't matter if they have a personal combination with each other, it's their ability to finish moves off whether it's from (Tom) Cleverley, Nani or (Antonio) Valencia. But Robin's second goal was absolutely fantastic. It was a good ball from Wayne. I thought he hit it too far in front of Robin, but his speed to get to the ball and deftness of touch was fantastic. Van Persie heaped praise on Rooney's contribution before admitting that he is now targeting more assists to go with the goals he has already delivered at United. Everything starts with a good pass, so I have to thank Wayne for that (second goal). Van Persie said. Not many players can make a pass like that. When it came to him, I knew he could see that pass and give it the way I wanted it. I think it is the first time we have started together, we were both really pleased with that. We did it together tonight. But I would like to make more assists. It is not only about goals but I want to make more assists. I would like to improve that. Rooney, making his first Champions League appearance of the season, added: "It's difficult in the Champions League and we know that it was a silly goal to give away early on. Thankfully we managed to get back in the game. If we get three points in the next game, we'll be in a great position in the group. Despite the poor goal United conceded Ferguson was satisfied with the overall defensive display. I'm really pleased that the possession was really good tonight and apart from their goal I think we defended really well.
