I saw an interesting statistic someone pulled up, leading one to believe we actually dont need a striker as much as we thought. That is, we have scored as many goals now as we had at this point last season, on almost the same number of points.
Also interesting, Rooney has a better goalscoring record this season than Lukaku. Niasse is on pace to blow it away. So it would seem our real issue at this point of the season is defence. Of course some of that is coupled with our lack of ability to keep posession up top and in the midfield, thus putting more pressure on our defense. So its not our goalscoring that we need to replace in January(although improvement would be good) as much as improve our defence and inbetween play.
