Nestor Lorenzo acknowledged Colombia must be "the best version" of themselves if they are to beat Argentina in Sunday's Copa America final.
Los Cafeteros are gearing for their first appearance in the tournament's showpiece since lifting the trophy on home soil in 2001.
Lorenzo's side topped Group D ahead of Brazil with seven points from nine, before inflicting a 5-0 rout on Panama in the quarter-finals.
Colombia then edged out Uruguay 1-0 in the semi-finals - despite playing over half the contest with 10 men following Daniel Munoz's dismissal - to stretch their unbeaten streak to a national record of 28 matches.
Lorenzo is delighted by the way his players have overcome the different challenges presented to them en route to the final, where Argentina await.
However, he knows they must produce a perfect performance if they are to dethrone the reigning Copa America and world champions.
"We need to be the best Colombia, the best version, to beat Argentina, the champions of everything," Lorenzo told reporters during his pre-match press conference.
"To win against Argentina, we have to be very well-prepared, because they are the champions, it will be a very demanding match," he added.
"Every day, overcoming an obstacle means you grow, and we have had several games with these types of situations that made us reinvent ourselves in the game and the team reacted.
"We are in a very good moment. I think the team still has room for improvement, and we hope to have a great performance tomorrow and take a step forward in that sense as well."
Injury forces Militao out of Brazil's World Cup qualifiers
Eder Militao will miss Brazil's upcoming World Cup qualifiers against Chile and Peru due to a thigh injury.
The defender, who also missed September's fixtures due to a leg injury, first felt some discomfort against Atletico Madrid on September 29.
Though he has featured for Real Madrid since, he flew out to Sao Paulo to undergo checks on the issue, where the national team confirmed the extent of the injury.
"[Militao] underwent tests this Sunday... which revealed a minor muscle injury in his left thigh that will prevent him from playing," the CBF said in a statement.
He is the second Madrid player to pull out of the Brazil squad, with Vinicius Junior also unfit to play after suffering a neck injury.
Brazil sit fifth in South America's qualification table after eight matches, with 10 points.
Brighton 3-2 Tottenham: Rutter inspires remarkable Seagulls comeback
Brighton managed a remarkable second-half comeback as Georginio Rutter scored one and played a key role for another in a thrilling 3-2 home victory over Tottenham.
Ange Postecoglou's visitors had won their last five games, including their EFL Cup and Europa League exploits, and started well on Sunday as in-form Brennan Johnson scored for a sixth straight outing.
James Maddison doubled the away side's lead before the interval, aided by Bart Verbruggen's handling blunder, but Yankuba Minteh halved that deficit after the restart with a thumping finish.
Destiny Udogie was somewhat at fault for Minteh's finish, and the Spurs defence again struggled as Rutter restored parity before the hour mark after dancing around a couple of defenders.
Former Leeds United star Rutter then edged past numerous Tottenham charges once more, with his cross deflecting up for Danny Welbeck to head in the 66th-minute winner and seal a memorable turnaround.
Verbruggen was still required to deny Udogie late on, however, as Fabian Hurzeler's side held on for a victory that lifted them to sixth and ended Spurs' impressive winning run.
Data Debrief: Johnson's heroics in vain
Johnson has now scored in each of his last six appearances in all competitions, becoming the first Spurs player to do so since departed talisman Harry Kane between December 2018 and January 2019.
The winger's six goals across 10 appearances this season are also more than he managed in 34 outings for Spurs last campaign, though Johnson's efforts proved ultimately in vain.
Sunday marked the 10th time that Tottenham have lost a Premier League game in which they led by two or more goals – they are the first club to hit double figures for this, and have done so three more times than any other club in the competition's history.
Indeed, this memorable turnaround saw Brighton win a league game after trailing by two or more goals at half-time for the first time since a 3-2 victory against Charlton in the Championship in December 2015.
Al-Ahli 1-2 Al-Hilal: Mitrovic double keeps Saudi champions perfect
Aleksandar Mitrovic proved to be the difference once again for Al-Hilal as the reigning Saudi Pro League champions beat Al-Ahli 2-1 on Saturday.
Al-Ahil went in front with 12 minutes played when Gabri Veiga was sent through on goal by Franck Kessie, with the Spaniard rounding Yassine Bounou to open the scoring at King Abdullah Sports City.
The hosts went close to doubling their advantage soon after, with Riyad Mahrez and Ivan Toney going close, before Sergej Milinkovic-Savic saw his effort cleared off the line at the other end.
But parity was restored early in the second half through Al-Hilal's master marksman, as Mitrovic nodded home a trademark header from Renan Lodi's delivery.
Al-Ahil were then awarded a penalty when Rayan Hamed fouled Malcom inside the box, only for Mitrovic to see his effort saved by Abdulrahman Al Sanbi.
However, the Serbian was given the chance to redeem himself after the VAR deemed encroachment had taken place, and he made no mistake at the second time of asking to net his 14th goal of the season in all competitions.
Data Debrief: Mitrovic the main man
Mitrovic has been in fine form since his move to Saudi Arabia, with his latest double taking his tally to 54 goals in as many appearances for Al-Hilal.
This time out, he contributed 1.16 expected goals (xG) tally to the visitors' 2.24 total, while also recording the most touches in the opposition box (six).
Malcom also impressed for Al-Hilal, creating more chances (three) than anyone on the pitch, with his 14 passes into the final third a total only bettered by Ruben Neves (18) and Salem Al Dawsari (15) among his team-mates.
