I know it's twitter discussion thread and we can share our views etc. why don't we just trust our manager, if he wants Cavani I am sure he will have a plan for Rooney and other strikers. I don't expect Rooney to take the ball from midfield dribble pass players and score a goal - he has his strengths, surely he can make a short or long pass or make clever runs from midfield.
I won't mind spending my dollars to watch Cavani play for us. The more competition we have in our team for each position the better it is, let's just the manger worry about where he will fit in his new signings.
