It's satisfactory. They along with the others who came in all fulfill a purpose right now and a couple like Diaz and Gray cover a longer term requirement for the squad. AMN if he performs well and has an option to but may also be a shrewd longer term move.
Getting shut of the deadwood is looking desparately poor again.
I'm no Benitez fan, but he achieves anything with this squad this season (e.g. European qualification or dare I say a cup) he'll need zero injuries to the first team and a lot of luck. We're strictly in the 7-11th group in terms of playing talent of the squad.
