I think it has been written many times here. Lewandowski is not a player who is consistent. 4 out of those 10 goals were in one game. Do we need a striker who will score three goals against United and disappear in the next three games against Stoke, Villa and Everton? I guess you want an Eastern European striker in our team but there are better players that we can get. With Khedira coming out of bench they might score one or two goals. If they had someone like Vidal they would be in the final, that is the difference between an average Dm and the better ones, As I said before Lewy and Khedira are very good players for Tottenham. Defoe and Parker are getting old.
