John Terry was sent off as Pedro inspired Chelsea to a first Premier League win of the season at West Brom.

Thibaut Courtois saved James Morrison's early penalty but Pedro, who signed from Barcelona for £21m this week, fired in before setting up Diego Costa.

Morrison then atoned for his earlier error with a crisp strike before Cesar Azpilicueta made it 3-1.

Terry saw red for a second-half foul on Salomon Rondon but Morrison's header was not enough as Chelsea hung on.

The result ended a poor start to the season for Chelsea, who have raised as many talking points off the field as on it following controversy surrounding the treatment of their medical staff and Terry's half-time substitution in the 3-0 loss at Manchester City last Sunday.

And in another eventful game for the champions, Jose Mourinho's side will face further questions as Terry's dismissal gave West Brom a huge lift following a first half where Tony Pulis's team were outclassed at times.

Unlike their previous two games, though, Pedro provided them with enough inspiration to build the foundations for an edgy win.

Relive Chelsea's win over West Brom

Man of the match Pedro inspires on debut

Pedro

Pedro combined well with fellow Spanish internationals on his debut

After beating Manchester United to sign three-time Champions League winner Pedro, Chelsea benefitted from the 28-year-old's pace and incisiveness as the club's Spanish international contingent scored three times before the break.

Mourinho had criticised some of his players after earning only a point in their first two games, but Pedro gave their attacking an extra thrust, particularly on the counter attack.

Having already played alongside Cesc Fabregas while at Barcelona, the new recruit was heavily involved from the start, also linking well with Eden Hazard, who had his best game of the season so far after often coming inside to join-up with play.

It was from that combination that Pedro grabbed the opener, while his quick thinking was evident as he set up Costa from the second, the attack stemming from a West Brom corner.

As the game wore on, Pedro's influence faded before he was replaced six minutes from time, but it was more to do with Chelsea being reduced to 10-men after Terry's shaky start to the second half.

Further questions over Terry

John Terry

John Terry failed to finish consecutive Premier League games for the first time, having started both

Having been substituted at half-time against Manchester City last Sunday, Terry was included alongside Kurt Zouma at the heart of the central defence as Gary Cahill made way.

But England international Cahill was on the field by the 56th minute sporting a faceguard following Terry's dismissal where he was outpaced by West Brom's record £12m signing Rondon, who was making his debut after signing from Zenit St Petersburg.

The Venezuelan international had already set up Morrison's first goal before he latched onto Chris Brunt's through ball and was tugged back by 34-year-old Terry.

Despite the Chelsea skipper's complaints, referee Mark Clattenburg appeared to make a good decision as Rondon bore down on goal with the initial contact coming outside the penalty area.

Rondon's resulting free-kick was deflected over but he made an encouraging debut.

Rondon shows promise in place of Berahino

Salomon Rondon

Salomon Rondon caused problems for Terry before the Chelsea skipper was sent off

Rondon's inclusion came after West Brom boss Tony Pulis took the decision to leave Saido Berahino out of his squad following interest from Tottenham, who are reported to have had a £15m bid rejected by the Baggies.

Pulis complained before the game about the transfer window affecting players' concentration but the manager will have been buoyed by Rondon's display.

The former Crystal Palace and Stoke manager accepted criticism for playing with two strikers in their opening defeat by Manchester City, but he was far more cautious on this occasion and did not introduce forward Rickie Lambert until Chelsea were down to 10 men.

He could look back on Berahino's omission with some regret, though. As their regular penalty taker, he may have saved Morrison's early embarrassment, particularly as the Scottish international insisted on taking the spot kick ahead of Chris Brunt after a lengthy discussion.
