The 26-year-old made his international debut against the USA in November, becoming the first Bournemouth player to score for England. It was his 10th goal in 19 games for club and country this season.
Blues boss Maurizio Sarri is unimpressed by Alvaro Morata, 26, and Olivier Giroud, 31. The former is linked with a move to Barcelona but is struggling to adapt to life in the Premier League with just 16 goals in 45 league matches since his £60m move from Real Madrid in 2017.
Giroud, meanwhile, is a useful replacement but not a prolific goalscorer. The France international hinted recently that he would be interested in leaving Stamford Bridge in January in his pursuit of first-team football.
While Chelsea are reportedly confident of landing Wilson in a £30m deal, Eddie Howe will not let the former Coventry City striker leave without a fight:
“Callum is focusing on his football and we are not anticipating losing any players in January we don’t want to.
“He seems very happy, he has a spring in his step, he is buzzing around the training ground and there is a very good feel about him.”
