United States coach Jurgen Klinsmann will be taking no chances in their World Cup 2018 qualifier against Trinidad and Tobago on Tuesday.
USA began their campaign with a resounding 6-1 victory against St Vincent and the Grenadines, despite an early scare when Oalex Anderson put the visitors ahead inside five minutes.
The victory was Klinsmann's 43rd as coach of the national team, though he trails Bruce Arena's record of 71 wins accumulated between 1998 and 2006.
Trinidad and Tobago reached the quarter-finals of the 2015 Gold Cup, suffering elimination at the hands of Panama, who went on to beat USA on penalties in the third-place play-off.
The German believes such form warrants due care from his side.
"I think Trinidad and Tobago and probably Haiti have been the biggest winners or surprises in CONCACAF this year," Klinsmann told USSoccer.com.
"They played a very good Gold Cup and also had some good results in friendlies and other test games.
"You have to give Trinidad and Tobago a lot of respect. They’re known for their physical game and known for being strong.
"A lot of their players play in the English Championship and obviously playing at home they have a lot of confidence, and they want to prove to the world that they’re a good team."
