The Premier League side are in Germany for the mini tournament of the Europa League.
They face Sevilla on Tuesday, and Neves admits the Spanish side may be more used to playing in such warm temperatures.
Neves told reporters: "[The heat] is maybe the only thing they have ahead of us. We are not used to this weather in the UK so they are a bit in front of us in that aspect - but it's the only one.
"We are professional and we have to be ready to play in all conditions, so there is no problem. We need to be ready for them - but they need to be ready for us.
"We are a squad and a team capable of great things. We had a great season, scoring more points than in the previous season and finishing seventh again.
"We want to go higher and we will give our best to win this competition and play European football again, but we need to be proud of ourselves. It's not easy for a team promoted from the Championship to finish seventh two years in a row and reach a European quarter-final."
