Angular2 Google Maps panTo not working (does nothing)

I'm using Angular Google Maps (latest @agm/core) but can't get panTo or setCenter to work it simply does nothing.

I import GoogleMapsAPIWrapper like this:

import { GoogleMapsAPIWrapper } from '@agm/core';

I then inject it into my constructor:

constructor(
injector: Injector,
private _wrapper: GoogleMapsAPIWrapper
){
super(injector);
}

Then I try to call the above method in a function like so:

resetMap():void
{
  this._wrapper.setCenter({lat:53.097900,
  lng:-1.661963});
  this._wrapper.panTo({lat:53.097900,
  lng:-1.661963});
}

I have also tried referencing the map as a ViewChild of type AgmMap but there is no public property to setCenter or panTo, as below;

@ViewChild('agmMap') agmMap:AgmMap;

Is there a way I can reference the google map control directly instead of the angular wrapper?

Please can anyone advise what I'm doing wrong? or how I am meant to reference the map to call methods against it.
