For Frank Lampard, this was the second league defeat in a row and a painful one at the hands of a former club for whom there is nothing but intense dislike on both sides.
Abraham has been a key player for the west London side this season, top scoring with 11 goals in 20 appearances.
The Chelsea manager is quite rightly being extolled as a breath of fresh air at Stamford Bridge and in the Premier League this season, but this was a day when two of his old bosses proved that there is more to management than youthful exuberance and being the next big thing. "It gave me a look at where we are physically", he said.
"Once you see the stretcher coming out you fear the worst".
"For me the most hard thing this week was not being anxious about the job or what was happening in the future, it was to convince the players not to change the style even though we weren't having the results we needed", Pellegrini said.
"We were consistent and consistent throughout the game, but we didn't come here to try to design, so this team has to play".
"If that was clear then we're looking at, just mainly, an impact injury".
"Heavy bruising could potentially risk his movement and his mobility around that".
The likes of Tammy Abraham, Mason Mount and Fikayo Tomori have all thrived, with Chelsea defying pre-season expectations to emerge as genuine top-four contenders once again.
"Shocked isn't the word, I'm more disappointed", said Lampard.
"But when I spoke with him in the week I could see he was prepared".
"I know people point to the circumstances but he has Olly Giroud - a World Cup victor".
"He (Abraham) has made the position his own in the short term".
When asked whether Pellegrini to play Anderson as No.10 against Chelsea saw him deliver a better performance, Bent told Football Insider: "Yeah he did, but I like him playing on the wing".
'It shows we have still got the grit, the desire and the determination to go out there and put in a performance like that'. He wasn't just a good story, he was the easy Man of the Match.
