MTU have been linked with the hottest real estate in Thai football in Natarid Thammarossopon of BEC Tero. Nattarid has interested a few clubs including LA Galaxy according to one report. A report on TLO suggests the deal is as good as done and Tero are already lining up a replacement.
MTU have also been linked to 3 as yet (to my knowledge) unnamed Thai Port players.
Edit: Thanks to Marco at his superb Thai Port Blog for his comment:
"The three Port players are rumoured to be Ekkapoom Potharungroj (quality winger/midfielder), Todsapol Lated (good young centre back) and Mongkol Namnuad (decent left back, free-kick specialist)."
