David Moyes' unveiling at Premier League strugglers West Ham United has sparked a big response from Sunderland fans and the wider football world.
The Scot, who resigned as Sunderland manager in the summer after the Black Cats were relegated, has taken over from Slaven Bilic at the London Stadium.
Here is the best of the Twitter reaction to his appointment, a move which has left some Sunderland fans shocked.
TFS_Sunderland tweeted: "For #WHUFC fans wondering what they'll get with Moyes, they need to hope it isn't the same as #SAFC."
Tony Shepherd wrote: "Bet he is a success. Just like Big Sam will be if he goes to Everton. Lets just go down have a clear out and get new owners."
John Jeffery tweeted: "Why the hell would ya take him when ya in the drop zone, look what he done with us. Far too negative and can't man manage!"
George Gifford wrote: "Absolutely hilarious!!"
Funky Bri tweeted: "He'll do alright with their squad. They're not a fraction of the state we're in"
Mark Dønoghue said: "Allardyce had them playing really well Jan-May 2016, finally looked a stable and settled side... Then Moyes came in and destroyed #SAFC."
Liam Brown added: "Something good might come of Moyes at West Ham...he might come and take Gibson off our hands #SAFC"
Scott tweeted: "Wonder what the odds are for #Moyes to be the next Premier League manager sacked?"
Simon 'SAFC' Gibson said: "David Moyes' agent deserves one almighty Xmas present for this deal. Let's hope he takes Rodwell, Gibson and a few others 2 #WestHam. #safc"
Ghost of Les added: "If BSA had stayed #safc would have been mid table. Yes they've struggled but Moyes was horrendously bad."
Stephen Gray added: "Le Tissier reckons safc on downward spiral when DM took over. Allardyce took 26 points in half a season. Moyes had 24 full season. 24. #safc"
