Uzbekistan led 1-0 at the break following Odil Ahmedov's curling free-kick at the Sharjah Stadium.

Oman, however, clawed their way back into the game when substitute Muhsen Al Ghassani pulled his side level in the 72nd minute.

But with five minutes left, Eldor Shomurodov produced a moment of brilliance after coming on as a second-half substitute to ensure Cuper’s men got their UAE 2019 campaign off to a winning start.

The win took Uzbekistan to second in the standings behind Japan, who defeated Turkmenistan 3-2 in their opening tie earlier on Wednesday.

Oman started aggressively, as they tested the Uzbekistan defence with several surging runs and in the 14th minute, came close to scoring through Ahmed Al Mahaijri’s header which goalkeeper Ignatiy Nesterov brilliantly saved.

Oman’s confidence grew as they pegged the White Wolves in their own half and in the 25th minute, Saad Al Mukhaini’s delivery from the right flank sailed invitingly for Raed Saleh but the forward failed to connect.

The four-time Asian champions went into the break trailing 1-0 after Arslanmurat Amanov’s stunning long-range strike had threatened to earn Turkmenistan their first-ever victory at the continental Finals.

However, a much-improved Japanese display after the break – which saw Yuya Osako score twice and Ritsu Doan add a third – proved enough to seal all three points for Japan despite a late scare courtesy of Ahmet Atayev’s 79th minute penalty.

Trailing 1-0 at half-time, Yuya Osaka’s brace and a goal from Ritsu Doan proved the difference in a game which had seen four-time champions Japan trailing at half-time before a spirited revival ensured all three points for Hajime Moriyasu’s charges.

The result takes Japan to the top of Group F where they are level on points with Uzbekistan who beat Oman 2-1 in the group's later game.

Second-half goals from Bassam Al Rawi and Almoez Ali gave the 2022 FIFA World Cup hosts all three points at the end of a challenging encounter to move Sanchez’s team level on three points with Saudi Arabia at the top of the early standings.

That sets the stage for an exciting battle as the UAE, expected to be backed by a capacity crowd at the Zayed Sports City Stadium, look to bounce back with a win after being held to a 1-1 draw by Bahrain in their Group A opener on Saturday.

For India, another three points would surely mean a place in the Round of 16 after their impressive 4-1 victory over Thailand on Matchday One.

Both teams need to win, with Bahrain having conceded a late goal in their 1-1 draw with the United Arab Emirates while Thailand suffered a 4-1 defeat to India.

Bahrain looked set for the three points after taking the lead against UAE with Mohamed Al Romaihi breaking the deadlock in the 78th minute but were denied victory when Ahmed Khalil converted a spot-kick 10 minutes later.
