Ferguson confident over Rio injury
Ferdinand limped out of United's 1-1 draw with Valencia in the Champions League on Tuesday after reporting discomfort in his hamstring. The problem has been described as minor by Ferguson who feels that with six days to recover, the 32-year-old will be fit to face Arsenal.
"Rio has a tight hamstring and we couldn't take any chances with the game against Arsenal next Monday," Ferguson said. "It's a tight hamstring, not a pull, so I'm sure he will be okay for the game but we weren't prepared to take any chances.
"He felt it at half-time and wanted to see how it went, but he should be okay because he's got six days to recover."
Paul Scholes is also unlikley to make the game. "Paul tried training on Sunday and came off,'' Ferguson told MUTV. "He will be doubtful for next Monday.''
Anderson scored his first goal for United at Old Trafford in the 1-1 draw and Ferguson feels it could act as a spark for the midfielder.
"He should get more [goals]," Ferguson said. "He's a terrific talent. He has great pace and power. We're pleased he got the goal and it may help him."
• Goalkeeper Ben Amos is hoping to build on his Champions League debut for Manchester United by spending a short period away from Old Trafford.
"It is crucial for a young goalkeeper to get a good run of games,'' he said. "That is how you get experience. The only way of doing that is by going out and playing regularly somewhere. If it means me going out on loan somewhere, that might be great.
"The manager told me what he thought of me at the end of last season, which was great motivation. I was grateful for that. When someone of the stature of Sir Alex Ferguson has that belief in you. It gives you great confidence. I don't know what is going to happen with Tomasz or any other goalkeeper at the club.
"But, if I am being honest, a loan move is something I would like. I would benefit a lot from it. Now that we are out of the Carling Cup there are fewer opportunities for me to play anyway and it could be just the thing to take me to the next level.''
