Manchester United may have scored three goals to collect all three points this afternoon, but that didn't leave them immune to some rather vociferous criticism after the final whistle.From the moment Jesse Lingard scored it was never in doubt that United would come away empty handed, though Middlesbrough gave them a late scare when Rudy Gestede pulled one back for the hosts.Boro broke their duck of not having found the net in a shocking 510 minutes of football, and in doing so managed to put United on edge for the final 10 minutes of the match before Antonio Valencia ensured there would be no fight back with a third goal at the death.The win has seen United leapfrog Arsenal into fifth, but rather than celebrate that fact, the focus has instead been on Jose Mourinho's tactics.Instead of going for broke up top, the Special One instead seemed to be deploying a system that had him playing six at the back against a side that couldn't hit a barn door with a banjo before this afternoon.This included playing four centre-backs and two wing-backs with Antonio Valencia, Phil Jones, Chris Smalling, Eric Bailly, Marcos Rojo and Ashley Young making up his defensive unit.Clearly wary of suffering from playing three games in six days, Mourinho wasn't going to take any chances with his defenders suffering from complacency.But that didn't stop a whole host of fans taking to social media to criticise the Red Devils boss and tease United for their incredibly heavy defensive unit against a side sinking back towards the Championship at an alarming rate.

Still, as funny as that may be, you can't argue with results as his tactics clearly worked. Whether you're playing teams at the top of the bottom, all that matters at the end of the day is three points.

The victory was United's 600th in the Premier League, which is a reason within itself to celebrate, though the performance may not have been vintage to match it.

United's players will no doubt be looking forward to something of a rest now that the international break in in effect. Having faced Chelsea on Monday, they met FC Rostov for the second leg of their Europa League tie before today.

The threads were coming loose on thursday as Marcos Rojo was so tired he needed a banana to help get him through the game.

We wonder how many he ate at half time today...
