On a day where much of the focus at Stamford Bridge centered around two expensive defensive arrivals, the Blues continued with their annual tradition of loaning out a small army of players.

Among the loanees was American defender Matt Miazga, the 21-year-old who joined the Premier League giant in January from Major League Soccer's New York Red Bulls.

Never change, Chelsea.
