Some future club legends hit the ground running with a Man of the Match-worthy debut, and the immediate adulation of the fans.
Others, meanwhile, take a little longer to settle in. Patrice Evra was certainly in the second camp, as the former Manchester United Left-back claims that he was laughed at during his first few months at Carrington.
The Frenchman first arrived at United in January 2006, having been signed from AS Monaco for a fee in the region of £5.5 million.
According to the man himself, it took him a long time to meet the club's famously high standards, with many of his new teammates initially wondering why the club had bothered to sign him.

In a recent interview with Betfair, Evra revealed: "I love to be challenged in my life. I think that's when you see the best version of myself."
"I'll be honest with you, players like Paul Scholes, they said: 'Patrice I think you were a joke! I think we should send you back for free to Monaco!'".
Far from being intimidated by such comments, Evra claims that he worked tirelessly to get up to speed - and develop the physical game he'd need in order to thrive in the Premier League.
The 41-year-old recounted: "I remember some players like Rio Ferdinand and Wayne Rooney they were laughing at me in training when people were pushing me down because I needed to adapt my football."
"I was a skilful player, I didn't know that first you needed to be strong. So first I went in the gym, which I never did while I was playing in France."
He added: "When people talk about me, it's not like a need them to surprise myself but that's when I think, okay guys, now it's show time."
As we all know, Sir Alex's gamble on the French international paid off in the long-run.
Evra would stay at United for eight years, earning a Champions League winner's medal in his second full season, as well as five Premier League winner's medals.
After playing 379 times for The Red Devils, he'd go on to enjoy a successful spell at Juventus, where he'd pick up a further two league titles.
Stints at Marseille and West Ham United would follow, before he eventually called time on his career in 2018 at the age of 37.
