Born in Valašské Meziříčí, Baroš represented the Czech Republic international team in 93 matches, scoring on 41 occasions.

[11] He made his club debut in a UEFA Champions League tie away to Barcelona on 13 March 2002;[12] he played the last 16 minutes in place of Emile Heskey as the match finished goalless.

[20] Baroš would later claim that had manager Gérard Houllier stayed at the club after the summer of 2004, he would have put in a transfer request.

With Michael Owen and Emile Heskey having been sold and new signing Djibril Cissé out with a long-term injury, Baroš was now Liverpool's only senior striker.

[22] Despite being the club's joint top scorer with 13 goals, including a hat-trick against Crystal Palace,[23] Spaniard Fernando Morientes was preferred to Baroš in Liverpool's starting lineup for the League Cup Final, a match they lost to Chelsea.

[27] Baroš also received his first red card during the campaign, being sent off for a high challenge on Everton's Alan Stubbs in the Merseyside derby on 20 March.

[28] In June 2005, former manager Gérard Houllier, then with French club Lyon, made an approach to sign Baroš.

[30] Baroš moved to Premiership side Aston Villa for a fee of £6.5 million in August 2005, signing a four-year contract.

[32] He played a crucial role in Villa's League Cup second round victory against Wycombe Wanderers in September.

[33] He set up the first Aston Villa goal in a November match against Sunderland in dubious circumstances; back-heeling the ball, which "looked to have gone out of play" to Aaron Hughes.

Baroš failed to score at the start of the 2006–07 season, leading new manager Martin O'Neill to challenge him in October to prove himself before the January transfer window.

[48] He played no further part in that season's Champions League campaign, as he remained on the bench in the return leg as Lyon were eliminated.

[49] In May 2007, Baroš was accused of making a racist gesture towards his Cameroonian opponent Stéphane Mbia during Lyon's match against Rennes on 18 April.

[67] He scored a total of five times in ten matches before breaking his left foot in two places after a tackle by Emre Belözoğlu in the Fenerbahçe–Galatasaray derby on 25 October 2009.

[71] At the end of September, he scored his fourth hat-trick for the club against Istanbul Büyükşehir Belediyespor, although he failed to complete the game due to an injury.

[77] He returned from injury in a February match against Antalyaspor, coming on as a substitute, but was on the field of play just 15 minutes before receiving a red card.

[85] He made his club debut in August, appearing as a substitute in a 0–0 Süper Lig draw against Kayseri Erciyesspor.

[87] He suffered damage to his anterior cruciate ligament (ACL) in December 2013, ruling him out of action for the rest of the season.

[90] Following the end of the 2015–16 season, Baroš left Mladá Boleslav and signed a two-year contract with Slovan Liberec.

[92] On 3 July 2020, 38-year-old Baroš announced that he would retire from professional football at the end of the Czech season, due to persistent injuries.

[4] Baroš debuted for the Czech senior squad on 25 April 2001 in a friendly match against Belgium whilst scoring his first goal as well.

[94] He and national teammate Pavel Nedvěd were both shown the red card in a November 2001 qualification match for the following year's World Cup, as the Czech Republic were eliminated by Belgium.

[95] At UEFA Euro 2004, Baroš scored the first goal for the Czech Republic in their first game of the tournament, a come-from-behind 2–1 victory over Latvia.

[96] His second goal of the tournament came against the Netherlands; the Dutch team had taken a two-goal lead over the Czechs before Jan Koller scored from a Baroš pass.

[98] Baroš appeared as a substitute and scored the winning goal, as opponents Germany failed to advance to the next stage of the tournament.

[101] An injury to his foot, picked up in a match on 3 June, kept him out of 2006 FIFA World Cup games against the United States and Ghana.

[106] Baroš was banned indefinitely from playing for his national side in April 2009 after a breach of discipline, having attended a bar late at night.

[108] On 12 August 2009, Baroš marked his national team return with a goal from the penalty spot in the 3–1 home friendly victory against Belgium.

[109] The following month, Baroš scored a career high of four goals against San Marino, in a World Cup qualifier which the Czech Republic won 7–0.

[7] Baroš gained the nickname "the Ostravan Maradona" in his native Czech Republic due to perceived similarities with the Argentine footballer of the same name.
