The England international said in a post on Instagram: “I want to thank you for everything you have done for me and this team over the last 11 months. From day one the energy, desire and passion you brought to help this team get back on our feet and fight again was nothing short of a miracle.
“Not everyone from the outside will appreciate or even understand what we all had to go through this season to achieve what we did, but you kept everyone together and wanting to fight for each other right till the very end.

I look forward to seeing you standing on the touchline once again showing everyone what a great coach and man you are, I just hope they appreciate and show you the respect you deserve. Thank you and good luck Gaffa!”
