All a little case of history re-repeating

In 2004, in the course of Wayne Rooney's hat-trick debut for Manchester United, the Old Trafford outfit swept aside a weak Fenerbahçe side 6-2 at home.  Impressive, formidable, but then a few days at the weekend they draw 0-0 at home to Middlesbrough, underlining why this would be another season in which Sir Alex Ferguson's team would not win the league title.  José Mourinho, then at the peak of his powers and on course for the league title with Chelsea, quipped that Man Utd should have saved some goals from midweek for Middlesbrough.
Fast-forward 12 years.  Arsenal put Bulgarian champions Ludogorets to the sword 6-0, Mesut Özil scoring his first hat-trick since his days in the Schalke academy.  Everything seems rosy and they another home match against an underwhelming Middlesbrough team at the weekend, three points assured.  No.  The match at the Emirates against the side from the north-east finishes 0-0.  Mourinho, now in decline (my theory is that managers have a use-by date; his Man Utd's thrashing at the hands of Chelsea the next day adding to the evidence), declines to (or rather doesn't) repeat the quip, so I'll make it for him: Arsenal should have saved some goals from midweek to use against Boro.
Maybe not an exact case of history re-repeating but the similarities are uncanny.  Will this result on Saturday be emblematic of another failed title tilt from Arsenal?
