Morrison said: “I’m honoured and humbled to have been appointed head coach of this great football club.
“The togetherness we have displayed in recent months – as players, staff, directors and fans – shows the enormous power of the Albion when it’s focused on a collective goal. We must now use that passion and energy to set the club back on course for success.
“Right now, my focus is on preparing the team for our final game at Sheffield Wednesday on Saturday – but to go to Hillsborough knowing our fate has already been settled on the pitch is down to the hard work of everyone at The Hawthorns.
“I would like to thank everyone for their efforts during my time as interim – not least the fans who backed us to safety. I will never forget the end to the Ipswich game when it felt like it was us against the world, with the atmosphere off the pitch matching the efforts of the players on it. Here’s to more of that, please.”
