The United States and Wales battled to a hard-fought, physical 1-1 draw in their World Cup Group B opener at the Ahmad bin Ali Stadium in Qatar on Monday night.

Timothy Weah scored a classy goal in the 36th minute to give the US the lead at half-time, but Gareth Bale struck from the penalty spot late in the second half to earn Wales an important point.

The match was played in a fantastic atmosphere with Welsh fans drowning out Al Rayyan but meeting their match in the typically vocal US supporters, whose drums barely stopped beating.

A lively opening 15 minutes saw the US nearly open the scoring from a Wales own goal and a Josh Sargent header seconds apart, while both Sergino Dest and Weston McKennie were handed yellow cards for hard fouls.

Gregg Berhalter's side continued to look the more dangerous of the two and opened the scoring late in the first half when Weah cleverly finished off his chance from a quick-hitting counterattack after being played in behind the defense by Christian Pulisic.

The physical play continued after the goal, with Bale and Chris Mepham seeing yellow shortly before half-time for fouls on Yunus Musah and Pulisic, respectively.

It was a tale of two halves and Wales manager Rob Page made the key change at half-time when he replaced the ineffective Dan James with the taller Kieffer Moore, who was exactly what the side had been missing in the opening period.

And as play resumed in the second half, Wales forced the US to defend for long spells, while Matt Turner had to come up big in the 64th minute to tip a powerful Ben Davies header over the bar.

"It felt like in the first half we had a lot of energy, a lot of momentum," Weah said after the match. "And then coming into the second half we dialed down and Wales turned it up a notch. They started pressing us, they had most of the ball and I think at the end that's what really hurt us."

Berhalter brought on three subs as the half unfolded to help the US see out the match, with Kellyn Acosta, Haji Wright and DeAndre Yedlin coming on and Musah, Dest and Sargent making way.

With the US headed for a massive win to begin the World Cup, Bale drew a foul from Walker Zimmerman in the penalty area and delivered an unstoppable spot kick to beat Turner to level the game for good despite 10 minutes of second-half stoppage time.

"To go a goal behind against a good team like the US, we showed character, credit to the lads for coming back and getting a point," Page said. "When we got the penalty we knew who was taking it, one million percent.

"He's never let us down has he? It's all about Bale and rightly so."

The US finished with four yellow cards, the team's most in a World Cup match since drawing five against Germany in 2002, while Wales were twice cautioned in the game.

"Wales were very direct in the second half," Berhalter said. "They have a big team and they made it very difficult. They stepped up the pressure.

"But I thought the guys handled it well. We kept it up to the end, it was a hard-fought game and we left everything out there."

Next up for the US is a massive test against group leaders England on Friday, followed by a match with Iran, which lost their opener 6-2 to the Three Lions, on Nov. 29.

Looking ahead to the rest of the group stage, Weah added: "In a World Cup, the most important thing is that we didn't lose. We need to continue to do what we do best and keep working."
