Antonio Conte believes Ross Barkley can become the complete player after the England international completed a £15m transfer from Everton to Chelsea on Friday. Barkley, who saw a planned move to Stamford Bridge collapse on the final day of the summer transfer window, has signed a five-and-a-half year contract with current Premier League champions but will have to wait for his debut while he returns to match fitness following a four-month lay-off with a serious hamstring injury. The 24-year-old underwent surgery on the problem and last played seven months ago. Conte’s acknowledges Barkley will take time to recover his best form but insists the player can have a big impact at his new club.
