Tanaboon Kesarat is a versatile defensive player who is a Thailand national team regular. He signed for Port for the second leg of the 2019 season. Capable of doing a job in central defence or defensive midfield, Tanaboon is highly rated by many Thai football pundits. In recent seasons, however, he has suffered from recurring injuries, the first of which was sustained after a crunching tackle from former Port midfielder Atthipol at PAT Stadium. After leaving Muangthong in 2016, Port was his third club in as many years. Tanaboon has made important contributions in both midfield and defence since his arrival.
