United States 2 Turkey 1 Former Hull striker ensures fine send-off for United States squad

Arda Turan opened the scoring after 27 minutes for the visitors in front of more than 55,000 at Lincoln Financial Field in Philadelphia.

But former Hull City striker Jozy Altidore netted just before the hour mark to level things up and Fulham's Clint Dempsey struck the winner 15 minutes from time.

Turkey pressed early on and missed decent chances through Tuncay and Hamit Altintop, before America responded with wayward strikes from Dempsey and Benny Feilhaber.

Turkey's opener came from an American attack, as Jonathan Spector set off on a neat run.

When he was dispossessed, however, it allowed Turan to attack and he was unchallenged as he advanced and struck past Tim Howard.

Both sides could have scored just before the break, but Tuncay's shot was deflected narrowly over and Dempsey could not get on the end of Altidore's dangerous cross.

US coach Bob Bradley made four substitutions at half-time and one of the replacements, Robbie Findley, made an immediate impact for his struggling side.

Ten minutes after the break, he controlled well before shooting wide – then three minutes later he had a hand in the equaliser.

He played in Landon Donovan and the Los Angeles Galaxy striker narrowly avoided Turkey goalkeeper Volkan Demirel, selflessly setting up Altidore to tap home.

Turkey went looking for a winner, but when the goal arrived it came at the other end.

Again Donovan was the architect as, from a short throw, the former Everton man found Fulham striker Dempsey, who controlled well and finished.

Dempsey and Jose Torres narrowly missed chances to add a third for the hosts in the closing moments, but there was still plenty of encouragement for the home fans.

The US have one more warm-up game, against Australia in Roodepoort, before opening their Group C campaign against England.
