But that is not always true and you know it. The fact that players are more versatile helps the team fluidity, players can switch their positions and create chances by doing so, that is what chelsea does a lot for example, arsenal as well. The rigid approach you prefer is quite old fashioned in my view but can also work to some extent if executed well. If you want Van Persie scoring goals and finishing the chances then we don't need him and can buy Grant Holt, that's who he reminds me sometimes.. I think he benefits from his name and his friendship with gaffer, nowhere near top class what some people still thinks. I hope he only can get better in his, for striker, ESSENTIAL skill - finishing as he missed couple of sitters today and through the season and so cost us some points.. because apart that he is quite useless, can't press at all, has absolutely terrible stamina and movement, is also often offside as he lacks any piece of pace or acceleration so needs to time it perfectly and often goes too soon (not always his mistake).. his hold up play is okay but often slows the attacks in a final third in promising positions so the opposition players are back.. I just don't see much what he brings to the team apart average number of goals so far. Falcao looks at least like fighting.. but when you look at someone like Costa, you know you are watching different league, pace power, can take players on, perfect hold up play and can still poach a lot of goals, everything in speed, first I thought he was overrated when he came in but he is not he is brilliant.. You don't want hear anything about Aguero as he is maybe the best player in the league, great numbers and perfect overall play, can create chances for him and for the team because he is not just finisher but perfect dribbler, can go past players, doesn't slow attacks down.. Not saying we need exactly welbeck but I think we would do better as a team with him.. I don't like the idea that defender only needs to defend and striker only scores the goals, maybe if they are absolutely top class and the team works for them, but there are so many players in the team that other players need to work for them. That is the point and Van Persie is not top class, no more.
