English Premier League: Is West Ham a threat to top four?

Today game really showed how West Ham are ready to follow and competes for top 4 race. As early kicked up for today derby West Ham were ahead of Tottenham in 5 minutes thanks to returning injured Antonio before loanee Lingard continued his fine form with the hammer's early second half kicked off but Tottenham tried to made things to happened in 64 minutes as Lugas scored but his efforts was not enough to rescued Tottenham from the defeat as the game ended 2 - 1 in favour of Hammer's.
And history was made today as Jose Mourinho side conceded in the 5 minutes of both halves of the premier league game for the first time.
As it's stand now top four spot is unpredictable, even the premier league champion Liverpool are noway to be found, they are below top four zone even some big names are yet close to where West Ham. The only thing that I'm kind convince that they may likely kick out from the top four is their next four fixtures.
But in football game anything is possible but one thing that I really optimist about is that Hammer's may likely shock football fans all over the world and may likely pick champion league spot this season .
Please I will love to know your opinion concerning my write-up.
Thanks for reading.
