Manchester United boss David Moyes spent 11 years at Everton before taking charge at Old Trafford last June to replace Sir Alex Ferguson, who retired after managing the Premier League champions for 26 years.
Moyes' replacement at Goodison Park, Roberto Martinez, has acknowledged the success the 50-year-old achieved with the Blues, but hopes that the fans welcome him back with appropriate hostility during the two sides' clash on Sunday.
'We all know how important the game is and how vital the three points are', Martinez said in his pre-match press conference.
'All the nice welcoming is going to be after the final whistle. We have got a great understanding of who is coming back but we have to understand they represent the opposition.
'We will show the respect to David Moyes. His work has been terrific. As a former Everton manager, every Evertonian has got great memories of the job he did with the football club.
'(But) we need to make it as hostile as we can for the opposition'.
The Toffees have been in fine form under the former Wigan Athletic manager, winning seven league games in a row in their chase for a top-four finish in the Premier League and the Champions League qualification chance that comes with it.
However, defeat to Crystal Palace on Wednesday night saw them get knocked out of the fourth place by Arsenal, who are now one point ahead.
This Sunday’s clash with the Red Devils now holds even more importance, with Everton still to play Manchester City in their remaining four games this term. The atmosphere at Goodison Park will likely reflect that pressure, as United remain in the fight to qualify for the Europa League with the Blues and Tottenham Hotspur – the soon-to-be disposed champions have a game in hand and are nine points behind Everton in fifth, making this game a classic ‘six-pointer’ in the top half of the table.
Moyes will be hoping to avenge his side’s 1-0 defeat to his former club at Old Trafford back in December. On the other hand, Merseyside clubs Everton and Liverpool have taken nine points off Moyes so far this campaign, and Martinez will be keen on making it 12 points this Sunday at the Goodison.
