good luck finiding many wingers better than milner, he is a quality english midfielder and you should stick with him. wingers are the last thing you need to worry about with villa. keep it english, challenge yourself
carew didnt play well for me at all but it might be different for you. id grab ched evans, strong striker and very cheap. usually on man city reserves.
milner was pretty key for me when i won the triple with villa if im honest, one of the best english wingers imo. main thing for villa is sorting out the defense, getting a good gk and new striker.
