When a footballer moves to a Premier League club, whether from another team in the English top flight or abroad, it can often take them time to settle in.
Considering the magnitude of moves to Premier League clubs, with wages higher than ever before, something of a bedding-in period has to be expected.
And while that has once again been the case with some of the Premier League's summer transfers, take Victor Lindelöf at Manchester United or Gylfi Sigurðsson at Everton for example, others have flourished almost instantly since switching employers.
It's a testament to both a footballer's ability to integrate themselves into a new culture and the astuteness of elite-level scouting, with clubs knowing exactly who to sign, why they want to sign them and what the player will bring to the club.
Some of the summer signings have caught the eye so much, in fact, that Football Whispers has put together the best XI.
