Jamie Gittens may have been playing for Borussia Dortmund in their Club World Cup win over Fluminense on Tuesday, but, if Chelsea have their way, the England Under-21 international will be in the Premier League next season.
Chelsea face Flamengo on Friday and, after the return of on-loan Jadon Sancho to Manchester United this summer, manager Enzo Maresca has made no secret a key transfer priority is to sign a winger.
The Italian is keen to add competition for Noni Madueke, Pedro Neto and Tyrique George.
While the Blues are exploring other potential targets after initial bids for the 20-year-old failed, Gittens remains the club's first choice.
