Lagging when I am in the lead

Every time when I start the head to head match it starts smoothly but when I score a goal it starts lagging then the opponent score more goals the it kicks me out even when my network is okay.

I tried playing head to head and others to get +112 to 116 but it always gives me league one Mc Donald's every time since the Bundesliga started until now.

Fix your game Ea please.
