Appearing in the tournament for the first time since winning it a decade ago, the Uzbek outfit were in command from the opening whistle but took until the 53rd minute to take the lead through substitute Sukhrob Nurulloev.

Nurulloev’s goal proved to be the turning point, with Shohmalik Komilov, Khusain Norchaev and Khusniddin Alikulov all subsequently getting on the scoresheet in a match where Nasaf had 33 shots at goal.

Playing in their first competitive match in nearly six months, the Turkmenistan title holders suffered a major setback when Berdimyrat Rejebov was shown a straight red card after 17 minutes but managed to avoid defeat thanks largely to a first-half brace from star striker Altymyrat Annadurdyyev.

Having reached half-time level at 2-2, Altyn Asyr had to survive the final few minutes of the clash with just nine men following Mekan Saparov’s second yellow card but managed to avoid defeat against the group hosts.

Absent from continental competition since 2014, and still a second division club in their home country until the end of last season, Ravshan struggled to get to grips with their opponents early, falling behind to a pair of Elman Tagayev goals within the opening 20 minutes.

Half-time substitutions and a Daler Shomurodov penalty got the Kulob club back into the contest after half-time, but Gurban Annayev’s 63rd-minute goal put the contest to bed, meaning Ravshan could be eliminated even before their second and final group stage match next Thursday.

The Uzbek side dominated from start to finish, but were unable to find a break in the opening 45 minutes as Shohmalik Komilov and Marko Stanojevic both hit the crossbar from long range.

Alay’s only chance of the first half came against the run of play as Emmanuel Yaghr broke free from Tijani Belaid’s through pass but with just the goalkeeper to beat, he was unable to apply the finish.

The 32-year-old former Borussia Dortmund goalkeeper revealed he was quitting the international scene due to family commitments and the challenges created by the ongoing COVID-19 pandemic.

Also scheduled during the final tune-up are two friendly matches, including one against Ukraine in Kiev, as Bahrain gear up for Group C of the Asian Qualifiers.

Qatar, who were invited to take part in the tournament set for the United States, will make their debut appearance on July 13 at the BBVA Stadium in Houston.
