Being active in the transfer window doesn't necessarily mean that a club must sign certain players. What Manchester united are currently attempting to do might not just be the best decision for them in this window. They've secured Cunha and Mbeumo, which I think it is a very good deal, but going for Jackson?, hell no. He's not the kind of player that united needs right now. Why not keep Garnacho instead.

There are far more better players that Manchester united can get.
And is it a must that English clubs must get players from the premier league?, when there are actually lots of players from other leagues that the club can sign. Not all popular players are good enough for these big clubs like United. I hope they don't do the craziest thing in this remaining section of the transfer window.
