Man City Airport to Old Trafford

Hi guys, i´m wondering if there´s a tram from Man Airport to Old Trafford, since i can´t see on the Bee Network app itself ?
Also, is there anything to do in the surroundings of the stadium? My flight should land around 12h but we have our tour booked for 15h which i think it´s plenty of time. Or is it better to go to the city centre before?

Thanks!!!
