Chelsea goalkeeper Kepa Arrizabalaga admits Pierre-Emerick Aubameyang has been rocked by so many changes over the past fortnight.

Aubameyang left Barcelona for Chelsea, where he was hoping to be reunited with his former Borussia Dortmund coach Thomas Tuchel. But Tuchel was sacked last week.

After their Champions League draw with RB Salzburg, Kepa said: "The truth is that the first days he arrived a little scared. He was a little in shock, a lot of change, the last two or three days were very crazy for him, everything that happened to him was a misfortune."

On new manager Graham Potter, he added: “In the end it has only been a couple of days that we have been with him, it has been a bit of a crazy week.

"When a coach with whom we have had so many good moments leaves, it is always a bit sad. With the new coach, new ideas."
