Wrong water pump

Hey everyone

I'm doing the water pump replacement and I'm near the end but the pump looks entirely different than what I ordered.

The pump in my car looks bigger and it doesn't look like it has the hose on the back that the new one does.

I ordered it through fcp euro and it said it was correct but I have my doubts. Does anyone know if this is correct and I just have to keep at r or did I get the wrong one.

I have 2015 Golf SEL
