Expected it to be a ban tbh, but that's our best defender gone at a crucial time. Gerrard we can live without for 3 games but Lovren, Sakho and Can , looks like a very wobbly back line. None of them look like leaders and all of them look unsteady under pressure with the ball. Could well be top four chances gone now. I don't know, with the slip last year and the bans now this year, I swear that at times we cause ourselves to lose rather than the opposition beating us.
You have a relatively easy FA Cup tie and two EPL games which he misses.
The Arsenal game Utd could easily lose (its a complete toss up at that stage of the season imo even if Arsenal rarely win at OT in the EPL) and Newcastle away - well that team is changeable / inconsistent every week anyway
I honestly don't think its as dead and buried as you think
Looking at it another way, Utd need to aim for at least another 5 wins and a draw to make it even close to staying in the top four (baring in mind the form you were in before last weekend) - admittedly this is dependant on the Arsenal result in 10 days, but saying that it wouldn't be that surprising seeing you getting a better result vs Chelsea than Utd manage either.
That means Utd wining at home to Villa and West Brom and away to Everton, Palace and Hull (on the last day of the season remember) and trying to get a point from either the City / Arsenal (at home) or Chelsea (away) games
(edit - admittedly in one sense having the City and Chelsea games back to back and so near after the int break might help Utd IF a decent result can be got from one or both games)
Admittedly the above is based on form of both Utd and Liverpool prior to last weekend rather than points total average from the last few seasons which may require less points.
(and we have quite a few similar teams left too although away/home is different - Arsenal, Hull, West Brom, Chelsea & Palace face both teams)
edit 2 - there is also potential for Chelsea to have sealed the title already by the time you two meet at the bridge several weeks after they meet us - depending on City / Arsenal's form of course - which could help decide your result there.
