Ole came in having to dump two overpaid flops in Lukaku and Sanchez, had Martial and Rashford as his main attackers (both fringe players under Jose) and regularly had to play Lingard and Andreas Pereira as key attackers in his starting line up.
Louis's attack when he joined was Van Persie, Rooney, Chicharito, Welbeck. He had Nani, Zaha and Valencia on the wings and brought in Di Maria and Falcao straight away. Yet he regularly produced some of the most tumescent football ever seen at Old Trafford.
There is no doubt that Ole was a better fit for United than he would be for other clubs but he did a better job at United than Moyes, Van Gaal and Mourinho who moved on to get some pretty impressive gigs afterwards.
So, it was a tough enviromnent and he did a very good job and he should be very proud of that.
He's no Guardiola but he's a legendary player and did a very good job as manager. A true club legend.
