8 League games between now and January. 4 of them against Villa, Palace, Everton (home) and Burnley. The other 4 are more difficult on paper but even if we lost all 4 and Swansea in 5th won their corresponding 4 fixtures, we would only be 5 points behind them. Or we would be 4 points behind Arsenal if they won all 4 of their games.
Assuming we at least match Arsenal or Swansea's results in the other 4 winnable games, we are still going to be within striking distance of the top 4 come January. Maybe not in the top 4 but certainly in the mix.
