Alan Shearer reacts on Twitter to Sunderland thrashing, highlights Newcastle's biggest problem

The Newcastle United legend took to social media after Sunderland beat his old side 3-0 on Sunday afternoon.

So it's six in a row for Newcastle and Sunderland, with the Magpies being beaten by the Black Cats in the last six Tyne-Wear/Wear-Tyne derbies.

This particular derby had an air of controversy but it was still the same old flaws from Newcastle in the end.

And Alan Shearer summed things up as he took to Twitter on Sunday afternoon. Indeed, Shearer believes Steve McClaren's men suffered because they showed 'no cutting edge' against Sunderland.

Meanwhile, the former striker also gave his verdict on the penalty decision that changed the game. Defender Fabricio Coloccini was sent off for the Magpies and conceded a spot-kick. Shearer feels a penalty was the correct decision - but not the red card.

Many disputed the Argentine's sending off but it is clear he was simply stupid to unnecessarily barge Steven Fletcher in the first place.

On Newcastle's overall performance, meanwhile, they certainly did enjoy plenty of possession against Sunderland but paid the price for a lack of effort when it mattered.

Before the derby, McClaren suggested that this was 'just another game.' His players treated it that way and ultimately paid the price.
