John Hackworth believes St. Louis City's derby with Sporting Kansas City is key to MLS as they resume their rivalry on Saturday.
The last two meetings between the sides have finished level, with both ending in dramatic fashion.
St. Louis City come into the latest edition having lost just one of their last six outings, though that was their last home match.
They sit 13th in the Eastern Conference, level on points with Sporting above them, and Hackworth is now keen to build on the momentum from their win over San Jose Earthquakes last Saturday.
"We talked about trying to finish these last five games with a lot of momentum, showing our fans what we were capable of," Hackworth said.
"We knew we had to go on the road in one of these three games and be successful, and now we just need to build on that.
"This rivalry is really important to our league. It's two teams who are going to go after it and play by their principles, leaving it all out there to see what happens - two dramatic draws set us up for this contest."
Meanwhile, Kansas City have won just one of their last five matches in all competitions and suffered a 3-1 defeat to Los Angeles FC in the US Open Cup final on Wednesday.
Head coach Peter Vermes was left disappointed by the result but believes there are positives to take from the performance.
"I give the guys a lot of credit. I'm very proud of the effort that the guys put into that game," Vermes said.
"It never feels good to lose. But I also think that the group did themselves proud in the way they performed. We had good responses in that game, but in the end, we fell short."
PLAYERS TO WATCH
St. Louis City – Cedric Teuchert
Cedric Teuchert scored in the fourth minute in each of St. Louis City's last two matches.
Teuchert is one of six players to score more than one goal in the opening four minutes of matches this season and the second to do so in consecutive matches (Mikael Uhre).
Sporting Kansas City – Tim Melia
Both goals Sporting Kansas City conceded in their loss to Minnesota United on Saturday came in the final 30 minutes.
Sporting have allowed 31 goals in the final 30 minutes of matches this season, only San Jose (33) has allowed more, and Tim Melia will be hoping his concentration levels can improve ahead of Saturday's match.
MATCH PREDICTION: ST. LOUIS CITY WIN
St. Louis City have lost only two of their last 10 matches in all competitions (W4 D4), including picking up a 2-1 win at San Jose on Saturday. St. Louis have not won two straight matches in all competitions since wins over Minnesota United and Sporting Kansas City last September.
Sporting have lost 10 of their last 12 regular-season away matches, including a 2-0 loss in Seattle in their last league road match. Only league-worst San Jose (11) have lost more away matches this season than Sporting (10).
However, Kansas City are unbeaten in four straight meetings with St. Louis (W2 D2) after St. Louis won two of the first three encounters. This will be the eighth meeting between St. Louis and Kansas City, totaling 10.4 % (8/77) of all of St. Louis' games in all competitions up to this point.
