It isn't quite the start to the year Chelsea would have hoped for.
Slipping further and further behind Manchester City in the Premier League title race but still with a chance of winning four other competitions, Thomas Tuchel and his team needed only harmony.
Unfortunately, Romelu Lukaku decided to open his mouth and torpedo all of that. In just a couple of lines spoken during an interview with Sky Sport Italia, the Belgian striker has well and truly rocked the boat.
Lukaku, a club record £98million signing back in the summer, confessed to his unhappiness at Stamford Bridge, especially at Tuchel's choice of formation, and made no secret of his affection for former club Inter Milan.
