Chelsea is not a very dangerous team offensively. You still need to be worried about the wingers – Joe Cole, Deco and substitute Malouda are all dangerous – especially Cole, who has great long range shot ability. Besides that – watch out for Droghba headers, Ballack passes and Lampard long range shots. Essien will come forward many times to support the attackers – this is your chance for launching a counterattack, especially if full backs had also moved forward.
