Scotland lost their final Future Cup fixture to an impressive Turkey side at the Caledonian Stadium, Inverness.
Kilmarnock's Steven Naismith was on target for Scotland
The visitors raced into a an early lead when Salih Kabze's deflected shot beat Mark Brown and Sinan Kaloglu thundered in a second goal after 25 minutes.
Steven Naismith then found the net from close range but Tatab drilled in Turkey's third after the break.
Lee Miller headed in a Barry Robson cross before Ian Black and Orhan Ak were both dismissed in injury-time.
The victory means Turkey win the Future Cup event, which also included Germany, Poland and the Czech Republic.
The visitors started brightly and within six minutes Turkey had neatly played themselves into an early lead.
Kabze cleverly exchanged passes with Kaloglu on the edge of the penalty area and when the ball returned to the midfielder he clipped a shot past Mark Brown via a slight deflection from Steven Hammell.
And, with 25 minutes gone, the Turks doubled their lead thanks to a powerful 12-yard strike from Kaloglu.
Ceyhun Eris went close with a long-range thunderbolt and Brown made a fantastic double save to deny a stabbed shot from Eris and the follow-up from Arslan.
Scotland were being completely overrun but managed to pull a goal back three minutes before the interval.
A Barry Robson shot landed at the feet of Dargo and when his flicked effort was saved Naismith pounced to stroke home a simple finish.
Both sides made three changes at the break but the substitutions did not alter Turkey's domination and they scored again early in the second period.
Kabze's shot beat replacement goalkeeper Ian Turner but as the ball was hacked off the line by Adam Virgo, substitute Tatab was on hand to drive it low into the net.
Scotland again reduced the arrears when Robson found room to deliver a cross and Dundee United team-mate Miller glanced a deft header past Ercetin.
Scotland struggled to break down a well organised Turkey defence in the closing stages as the visitors comfortably played out the remaining time.
There was late drama as Black's strong challenge on Ak saw both players sent off in injury-time - the Inverness midfielder receiving his second caution for the tackle while the Turkish defender was dismissed for retaliation.
