Adeyemi told Cardiff City Player: “From the outside looking in, Cardiff City has a very strong squad that will challenge for a quick return to the Premier League this season.
“I took no persuading from the Manager to come here. It was a fantastic opportunity for me to work with somebody like him and to play for a club like Cardiff City.
"I’m very pleased that everything has been completed ahead of the season and now I can focus on fighting for a place in the side and helping us get the season off to a great start.”
Bluebirds boss Solkjaer added: “I’ve been keeping an eye on Tom’s progress for a very long time. A few years ago, my Manchester United reserve side played against Norwich’s first team and Tom was their standout player. He scored a great goal that day and stood out as a fine talent, even at that young age.
“Tom has a physical presence, drive and energy – up and down the pitch. He can dictate games and is great at winning and anticipating second balls. We’ve been interested all summer and I’m thrilled we’ve got our man ahead of the season kick-off.
“You need consistent performers in this league and Tom is one of those players who will fit in with Whitts, Gunnar and KG in that central midfieldarea. Those are guys that you can trust every single week to perform – they are all Premier League quality. We are looking to the future and we want Tom and the others playing for us in the top flight next year.
“What’s more, Tom is an intelligent young man with a great personality – the kind of character we want around the training ground. He plays with a smile on his face and we’re very much looking forward to seeing him perform for Cardiff City.”
