Sloppy Chelsea hand Tottenham and Man City Premier League lifeline
The Spain international was linked with a big-money move to China after rumours of a row with Blues manager Antonio Conte, and stats suggest it’s affected his form.
Prior to those stories breaking on 14 January, Costa had scored 14 goals in all competitions and was showing some of the form of his career.
Since then, however, the 28-year-old has netted just four times in eleven games in all competitions, with his conversion rate dropping from 24.14% to just 10.34%, according to stats from Goal.
