He mainly plays as an attacking wide forward although he has played as a conventional centre forward in the past. Amongst fans, he is principally known as 'Boa', and the 'The Dead Snake', (due to the general mistake of translating his surname into English) . His surname in fact in Portuguese means good death .
He started his professional career in August 1996 with Sporting, spending time on loan to junior club Sporting Clube Lourinhanense.
He made his debut on August 23 1997 as a substitute at Southampton. During Arsenal's double winning 1997-98 season he made 15 league appearances, mostly as substitute and four in the FA cup, although he did not appear in the final itself.
The following season he was a fairly regular squad member, usually as substitute in the early part of the season, with a few European Cup appearances, including against Panathinaikos on December 9 1998, when he scored Arsenal's third goal. His final appearance for Arsenal was as a second half substitute away to Sunderland on August 14 1999.
In only his second appearance for Southampton, away to Middlesbrough on September 11 1999, he was sent off for handling the ball in the goalmouth in the 77th minute, with Paul Gascoigne scoring the resultant penalty as 'Boro went on to win 3-2.
In January 2000 Dave Jones was replaced as manager by Glenn Hoddle, who dropped Boa Morte from the team. After Hoddle's appointment Boa Morte only made three further appearances and in July 2000 he had a trial at Fulham following which he moved to Craven Cottage, initially on a season long loan. As a result the first instalment on the fee due to Arsenal was never paid.
In his season at The Dell he made a total of 17 appearances, mostly as substitute, with one goal - a thundering left foot drive at Watford in a 2-3 defeat on December 28 1999.
His contributions to the Championship winning season, resulted in him being signed permanently in June 2001 (on a fee of £1.7 million paid to Arsenal), despite Southampton's attempts to bring him back after the expiry of the loan arrangement.
In Fulham's first two seasons in the Premiership, he was not able to replicate his form of the Championship winning season, scoring only three goals, although his form returned to some extent in 2003-04, since when he has averaged eight goals per season.
In August 2005, he was chased strongly by Newcastle United but pledged his future to Fulham and was made team captain. His crowning moment in a Fulham shirt was when he scored the only goal in the 1-0 win over Chelsea in the West London derby on March 19 2006 at Craven Cottage.
He became popular amongst Fulham's supporters whilst he played for them, for his impassioned, never-say-die and sometimes aggressive style of play - although this often led to problems with referees. He remains to this day a favourite amongst supporters for the service he gave to the club. Even though his form dipped towards the end of his Fulham career he will be remembered as a legend of his generation due to the excitement he gave to the Craven Cottage crowd on a regular basis.
He played his first game for the Hammers in an FA Cup tie against Brighton, setting up two goals and on January 13 2007 in the Premier League against former team Fulham. On April 28 2007, he scored his first goal for the club in an important 0-3 win against Wigan Athletic at the JJB Stadium. Many fans of West ham United believe his goal, the first in that match, to be one of the most important in that season, as they went on to survive relegation.
Despite an impressive season at club level, Boa Morte was disappointed to be left out of his country’s squad for the 2004 European Championships on home soil. However, the winger was part of Portugal’s World Cup 2006 campaign in Germany, playing in the 2-1 victory over Mexico on 21 June 2006.
Boa Morte currently has 25 caps and 2 goals for Portugal.
