you may dislike muntari or motta how you like, but i dont think the defensive abilities of hamsik are comparable to any of those two.
for me it sounds like comparing the defensive abilities of giovinco (hamsik) with nocerino ...
but as i already said, i did not see enough of hamsik lately to build an valid opinion about his defensive qualities.
i just thought what inter did not need is another attacking player ... i might as well be wrong
