More controversy with Pique in Vigo: was it a foul which led to Celta goal?

Barca were held to a draw by Celta Vigo at the Baladios. Despite the fact they have gone top of the league, they put the title on a plate for a Real Madrid side who can even draw one game for the rest of this season.
Just after Celta made it 1-1, Barcelona claimed a penalty on Leo Messi in an incident which saw Jacobo collide with him after the Argentine shot.
That was not the only controversial incident. Gerard Pique went down in the area after being pulled back by Nestor Araujo and the central defender complained about the awarding of the free-kick which saw Celta make it 2-2.

In the Barcelona defender's opinion, his former teammate Rafinha looked for the contact and dived on the edge of the box. Pique was not happy with the call.
The incident was talked about a lot on social media, where there was a variety of opinion over whether it was a foul or not.
