Memphis Depay wasted several opportunities to give his side the lead but apart from that, they lacked any real threat going forward.
The Catalonian side might even deem themselves fortunate to have got the point after Cediz created several chances to take all three points but Marc ter Stegen was equal to everything the home side created.
Speaking after the game, a furious Koeman said: ‘One of the problems is in Spain they send you off for nothing. They don’t say why, they just say attitude. Everyone saw the moment there was a second ball on the pitch. Everyone has to see that.
‘I am strong of course. I can’t win the battle with the press. I will put my energy into the team and with the players.
‘I still see a fantastic attitude of the players and for me that is most important. I can’t stop what the press are writing. We have to continue, that is my job.’

It’s now the second time this week Koeman’s side have dropped points, after the 1-1 draw to Granada on Monday. That follows the humiliating 3-0 home defeat by Bayern Munich a week ago.
