Thomas Tuchel's frustrated character on the touchline wasn't a good message for Chelsea fans. His annoyance during the damaging 4-0 loss to Arsenal was clear to see and his statement after the game was just as worrying.
Whilst pre-season should be judged with an air of caution, it is tough to have go through bad preparation and then bounce back quickly for the league, which starts in an all too soon 13 days for Chelsea.
The German himself admitted that he's a "huge fan of a strong pre-season in everything: atmosphere, feeling, performance, belief," something that has severely been lacking from Chelsea's tour of America, at least on the pitch.
