McLaren and Red Bull are in an argument about who employs Dan Fallows who allegedly signed for McLaren in January; however the lure of a higher placed job and more money has drawn him back to Red Bull. I presume that Fallows had to give a year's notice if his RBR contract had not run out so it could be that he can be asked to work it out instead of going on the usual "gardening leave".
