Arsenal fullback Kieran Tierney admits he endured 'sleepless nights' before joining the club.
The Scot left his boyhood club, Celtic, during the summer of 2019 in a deal worth £25m.
“I had sleepless nights. It was a hard decision," said Tierney.
“I knew how big Arsenal were. They are a massive club in a massive league. I'm coming down here and I'm playing in training against [Nicolas] Pepe, [Mesut] Ozil, [Alexandre] Lacazette and [Pierre-Emerick] Aubameyang every day. You're playing against the world's best players.
“It was obviously a great offer [from Arsenal], but I still had sleepless nights thinking 'what's the best thing to do here?'. It went on for ages.
“The first bid came in and I then signed on deadline day. At the same time, I was just coming back from my injury. I was like, 'Don't even focus on what's going to happen, just work hard and get fit, everything happens for a reason'.
"Arsenal are a massive, massive club and when I came I realised that."
