LONDON – Chelsea, somehow, remains fourth in the Premier League table, but that surely is not a position that can hold for long. Frank Lampard’s side was desperately unfortunate on Monday to lose 2-0 to Manchester United, but that cannot disguise the pattern of a miserable run of form that has seen it win only four of its last 14 league games. Tottenham is just a point behind now and United only three (and Sheffield United two). Regardless of whether Manchester City’s appeal against a UEFA ban ends up meaning the top four or top five qualifies for the Champions League, the pressure is mounting on Chelsea.
