Mason Mount, who is set to arrive at Old Trafford from Chelsea imminently, is believed to fit perfectly into the Dutchman's system.
Mount, in turn, was said to be hugely impressed by Ten Hag's eye for detail, as he snubbed new Blues boss Mauricio Pochettino to choose a move up North.

Mount had previously hoped to follow John Terry and spend his entire career in West London.
