Chelsea came from behind three times to earn a 3-3 draw with Johor Darul Ta'zim in a dramatic preseason friendly, with Liam Delap scoring twice from the penalty spot.
Johor took the lead after 14 minutes when Arif Aiman finished from the right side of the six-yard box following a pass from Marcos Guilherme.
Chelsea had already threatened through Delap and Nicolas Jackson, while Estêvão also went close twice as they searched for an equaliser.
Aaron Anselmino was then forced off through injury in the 29th minute, with Reggie Watson introduced in his place.
Chelsea eventually levelled shortly before half-time after Delap was fouled inside the penalty area by Kevin Medina. The striker stepped up and converted the resulting penalty into the bottom-left corner in the 42nd minute.
Delap almost grabbed a second before the break after Jackson sent him through on the counterattack, but his effort from outside the box went narrowly wide as the teams went into half-time level at 1-1.
Chelsea were awarded another penalty on the hour mark when Jamie Gittens was fouled by Óscar Arribas inside the area. Delap again took responsibility and converted from the spot in the 62nd minute to put Chelsea ahead for the first time.
Their lead lasted only three minutes, however, as Arribas made amends by scoring directly from a free kick, finding the top-right corner to make it 2-2.

Chelsea continued to push for a third, with Gittens testing Syihan Hazmi from distance, but Johor restored their advantage in the 86th minute through substitute Bérgson, who struck from outside the box into the bottom-left corner.
There was still time for another Chelsea response. Mykhailo Mudryk was introduced for Gittens in the 87th minute and Delap headed his cross wide two minutes later.
Chelsea found the equaliser moments later when Cristian Glauder turned the ball into his own net in the 89th minute to make it 3-3.
Johor almost snatched a late winner in added time, but Chelsea goalkeeper Gaga Slonina denied Arif Aiman from close range as the sides settled for a draw.
