The midfielder signed for Bournemouth earlier this summer for £10million.
The Cherries ran out comfortable 4-0 winners courtesy of goals from Callum Wilson (2), Lewis Grabban and an inexplicable own goal from the hosts’ goalkeeper Sammy Ndjock.
Cook recently joined Bournemouth from Leeds United for £10million and he will be hoping to impress in his first season in the top flight.
“Been a good trip and glad to get my first minutes for Bournemouth last night,” Cook wrote on Thursday afternoon.
The 19-year-old already has 85 first-team appearances under his belt from his time at Leeds, 47 of which came last season.
However he will not be a guaranteed starter at Bournemouth and he must ensure he works hard in pre-season to ensure he gives manager Eddie Howe no choice but to include him when it comes to writing the first team sheet of the campaign.
Cook will have seen his former Leeds teammate Sam Byram make just four appearances after moving to West Ham United in January and know the challenges ahead.
Bournemouth had a fine debut campaign in the Premier League and with some important players back from long-term injury – along with some canny additions – they will be hoping for even better second time around.
