When Jose Mourinho returns to Stamford Bridge as Manchester United manager this weekend he is sure to get an excellent reception from Chelsea fans after what he achieved in two spells in west London.
However, it doesn't sound like all of his former players at the Blues will be quite as happy to see the Portuguese boss.
That's after Victor Moses - a man on fringes during Mourinho's time in charge of Chelsea now making an impact under Antonio Conte - took a shot at the way 'The Special One' treated him in recent seasons.

"He never spoke to me," Moses said, via ESPN, when discussing Mourinho's decision to send him out on loan to Stoke City last season
"I thought in my head, 'He's got his own players already.'"

"I think we chatted a couple of times on the phone - he asked if I was alright at Liverpool [where Moses spent the 2013-14 season on loan], but that was it."
This lack of support and, indeed, interaction from his then manager can't have been encouraging for a player trying to break into the Chelsea first team.
Moreover, with Mourinho having always shown faith in a core group of players at Stamford Bridge during his two spells in charge, it isn't too far fetched to agree with Moses' claims of the manager having his favourites.
And, after three consecutive seasons out on loan, you can understand why the winger still appears to hold a grudge at the way his most recent short-term move was handled.
Things have turned around for the Nigerian international since Mourinho's permanent replacement, Antonio Conte, took charge.
After impressing during preseason, Moses has played well in the appearances he has made in the Premier League so far this season - scoring Chelsea's third goal in their win over Leicester City last weekend.
A key reason for his turnaround in form? The encouragement he has been given from his new boss.
"The manager came to me and said, 'I feel that you're working hard, I really enjoy watching you play and I don't want you to go out on loan'," Moses said when recalling a conversation with Conte before the season began.
"When he said that to me I was really pleased. To be honest, I just want to go out there, enjoy my football and work hard for him. He's played the game before, he understands it and he understands how players feel."
With Moses likely to keep his spot in Chelsea's starting XI for their clash with United this weekend, the 25-year-old will be hoping he can stick it to Mourinho with his actions on the pitch, not just in his comments off it.
