The German head coach addressed whether the Blues will look to make any further signings after their second successive Premier League win
Thomas Tuchel discussed transfers after Chelsea's win at Arsenal, admitting that "we maybe don't have the biggest squad".
Chelsea built on their 3-0 win over Crystal Palace on the opening weekend of the new season by beating Arsenal 2-0 at Emirates Stadium on Sunday, thanks to first-half goals from Romelu Lukaku and Reece James.
The Blues spent £98 million ($134m) to re-sign Lukaku from Inter after adding backup goalkeeper Marcus Bettinelli to their ranks on a free transfer, but have been tipped to dip back into the market before the August 31 deadline.
