Luol Deng broke his GB scoring record with 38 points, adding 13 rebounds as they survived being three down with 22 seconds remaining to seal place in the EuroBasket finals.

Pops Mensah Bonsu added 32 points and pulled down a massive 21 boards while Bosnia were led by 21 apiece from Henry Domercant and Ratko Varda.

Mensah-Bonsu opened the scoring with one of two free-throws, and despite Varda proving virtually unstoppable with six points, GB led 7-6 at the mid-point in the period.

Nihad Dedovic put the visitors 15-13 up with 15 seconds remaining, but Deng hit a pair from the line to send the teams into the first break tied at 15.

A Varda hook shot opened the second period, but a Mesah-Bonsu dunk put GB 23-22 ahead at the 6:40 mark before Domercant hit a trey to put his side back in the lead.

A Mensah-Bonsu slam off Deng's missed free-throw and a great bit of defensive work from Deng kept GB ahead by two going into the final three minutes of the half.

Deng picked up a second foul and technical for arguing after being clattered in the paint as Bosnia cut that lead to 39-36 going into the locker room, with Mensah-Bonsu on 17 points and Deng on 16.

Kenan Bajramovic tied the game with a trey to open the second half before Aleksej Nesovic also drained from downtown before Deng got GB off the mark with a midrange jumper and Reinking hit a trey to put GB up by two.

Back-to-back Deng threes put GB up by five but a Nesovic and-one made it 53-51 going into the final four minutes of the third period and they closed out the quarter well to lead 64-57 at the final break.

Bosnia hit the first five points of the final stanza before Deng drained a pair at the foul line, but a Domercant trey put his side 67-66 ahead with 7:11 on the clock to force a timeout from Finch.

Reinking hit a trey off Adegboye's assist as GB went into the final five minutes with a 73-69 lead but a big Domercant three pointer made it a one point game with 2:35 on the clock before Mensah-Bonsu nearly ripped the ring down with a dunk.

Domercant coolly drained three at the line after being fouled by Mensah-Bonsu to make it a one point game going into the final two minutes.

Bajrmovic reversed that lead with a lay-up before Deng missed a pair at the line only to see Bajrmovic hit a hook shot to force a timeout with 57 seconds on the clock.

Deng was sent to the line by Varda, who fouled-out in the process, with 21.5 seconds to go and he drained the first before Mensah-Bonsu got the rebound and was fouled.

He sunk both free-throws to tie the game with 18.7 seconds on the clock, and some tough defence saw Kojadinovic's shot kept out to send the game into overtime.

Deng hit the second of a pair at the line to open the extra period, but Bajramovic put his side back up again before he fouled out.

A Reinking floater made it a three point game before Deng's put-back made it 88-83 with 2:04 on the clock.

Deng's ally-oop to Mensah-Bonsu sent the Echo Arena crazy and put their team seven up before the former hit a jumper to make it a nine point game as GB wrapped up a place in the finals.

GB Head Coach, Chris Finch said after the win: "We said to our guys that all the teams we played against had the ability to hit shots. We had to hang in there till we got a rhythm going. Every time we had an eight or nine point lead we let them have it back. But there was a lot of pressure on us tonight, and we hung in there and it was a great win.

"Our team has great character. We all believed we could win every game even when we were down late. We responded well and made the hustle plays. Drew [Sullivan] got good stops, Pops made some huge plays and Luol was superb for us. But over all we have a mentally tough group of players."
