Asmir Begovic suffers nightmare Chelsea debut - but was he to blame for any of the four goals conceded against New York Red Bulls?

The Blues lost 4-2 to the under-strength MLS side

The true cost of selling Petr Cech may have been hinted at last night with Thibaut Courtois' new understudy conceding four goals on his Chelsea debut in a shock defeat.

Asmir Begovic arrived at Stamford Bridge to replace Cech who left for Arsenal. Signed for £8m from Stoke City, Blues fans would have been hoping the Bosnian would prove an adequate replacement.

However, his debut last night went horribly wrong.

Chelsea lost 4-2 to MLS side New York Red Bulls - a shocking result, but considering it was an understrength home side in New Jersey, the showing will have been of serious concern to Jose Mourinho.

After taking the lead through Loic Remy in the first half, in the second period things unravelled, despite the introduction of Diego Costa, Eden Hazard, John Terry and Nemanja Matic at the break.

Hapless defending saw the visitors concede four goals, with Hazard's strike the only consolation.

But was Begovic to blame? We take a look at the goals conceded...

1. Franklin Castellanos

Just moments before, John Terry had bailed out his new goalkeeper. But this back-pass from the captain put Begovic right in it.

Begovic at fault? Could have been quicker and more imposing, but the real blame goes to JT.

2. Tyler Adams

Some sharp passing by the hosts in the build up, but Cesar Azpilicueta did not get close enough to cut out the cross which was headed in by Adams, well out of the reach of Begovic.

Begovic at fault? Azpilicueta gets the blame.

3. Sean Davis

An absolute shambles of a goal from Chelsea's point of view.

Begovic at fault? Shot well struck into the corner from inside the box - little he could do.

4. Sean Davis

A dreadful attempted clearance from Ramires gifted the ball to Davis inside the box. The Red Bulls player smashed it right through Begovic from close range.

Begovic at fault? Should have got more behind the ball, but Ramires was ultimately the most to blame.

Mourinho conceded after the match that his new goalkeeper was not at his best.

"Begovic was not sharp, a consequence of being tired from training. In the next game against PSG he will start."
