size of squad

It was mentioned on MUTV tonight that with the arrival of Di Maria, Hernandez etc we will have a squad of 29 out in the US. Granted some of the younger players may not feature in the first team squad once the season starts, but surely there will be some trimming of the squad to a more manageable size prior to closure of the transfer market?! if we are indeed going to make a couple more additions to the squad (CB & Striker!!) - who do you see making way for them and leave the club, be it loan or sale?
