(Video): Mystery new arrival in training teased by Chelsea TV

Chelsea fans thought they might be in for a dull summer after their transfer ban – thankfully they had one signing already in the bank from January.

Christian Pulisic was signed from Borussia Dortmund way back on the first of January, but he’s only today arrived in Chelsea training.

The squad have only just got to Japan, but within hours their new teammate was there to meet them and join in training…

We can’t wait to see him in action!
