A host of Premier League sides were keeping tabs on Cook, after his impressive showings for Leeds.
At the time, Cook was very professional - and he rarely commented on the links suggesting that he was a target for a number of top flight clubs.
However, after leaving Elland Road, Cook has suggested that it was hard to keep focussed with so many rumours surrounding his future.
“It’s very hard,” Cook said. “You have to try put it to the back of your mind. At the same time, it’s quite exciting and you have to take the positives out of that.”
Despite the speculation, Massimo Cellino has insisted that Cook never asked to leave Leeds.
The 19-year-old remained one of the Whites’ most consistent performers last season, and his loss leaves a huge void in Garry Monk’s midfield.
Leeds have moved to replace Cook by bringing in the likes of Matt Grimes, but they are expected to have to bring in another midfielder before the competitive season starts.
Cook, meanwhile, is set to play a key role for Bournemouth - as the Cherries aim to further establish themselves as a Premier League club.
