From the start of the season Westham was so good and they tried to take it to this point but at this time they need to decide to be more focused on europa league or focus on England Premier league. It will be difficult to achieve both.
Here's the tricky thing about this week game. Even if Manchester city were to win against Manchester united, for West ham to overtake Manchester united, they would have to win their match against Liverpool which is unlikely (not saying is not possible). Sadly West ham would be playing against Liverpool first before the blockbuster game of the week.
The outcome of this game can also influence how that of the two giant will be played tomorrow. If Liverpool were to lose then Manchester city won't be under too much pressure but Manchester united would be more determine to win so as to retake the fourth position.
I won't forget though that we lost to West Ham in pretty bad fashion. Sure the scoreline was 3-2 so it looked close but the second goal was really more of a consolation than anything else -- we were disjointed even from reading the reports (I remember looking at the scores from mobile, was on the move that very day).
So yeah, it's a great week of games, with almost every game left with something to play for and draws not helping any of them, so I've gone mostly with results and not draws.
If Liverpool lose Pep won't admit it but you're right, he'll play with much more freedom.
