Chelsea's investment in Pedro paid immediate dividends but the 3-2 win at West Brom was marred by another bad day for John Terry.
Pedro played a starring role but John Terry was sent off as Chelsea claimed its first win of the Premier League season with a thrilling 3-2 victory at West Brom on Sunday.
Chelsea signed Pedro from Barcelona on Thursday and the Spain forward made an instant impact at The Hawthorns.
The 28-year-old opened his account for the champions with a deflected 20th-minute strike, but only after the returning Thibaut Courtois had saved James Morrison's penalty six minutes earlier.
