[4] Johnson's made a strong start to his career at Palace by scoring a hat-trick in the 5–0 thrashing of rivals Brighton & Hove Albion on 26 October 2002,[5] and then another, in the next match, at Walsall.
[6] Despite this, he made few appearances until manager Trevor Francis was dismissed[citation needed] with the Eagles mid-table, and replaced by Steve Kember.
[citation needed] With a return to fitness and form, the two soon became Dowie's first choice pairing as the season progressed, with Dougie Freedman adding experience to the strike force.
[citation needed] Palace comfortably made it into a top-six position but in the play-offs failed to recover from a first leg defeat at the hands of Watford,[16] being beaten on aggregate in the semi-final.
[citation needed] With Johnson having indicated a preference for a move to Merseyside, Everton, prompted by the two other bids, improved their offer to £8.6 million the following day.
[20] Everton manager David Moyes took the unusual step of contacting the Professional Game Match Officials Board in order to counter these accusations.
[citation needed] The board's general manager Keith Hackett agreed that Johnson was being treated harshly and had been denied several clear penalties.
[citation needed] He made only 13 appearances for Fulham in 2009–10, scoring three goals, as he missed much of the season due to a troublesome knee problem.
[citation needed] He made a good start to the 2011–12 season, scoring a Premier League hat-trick on 2 October in the 6–0 win over West London rivals Queens Park Rangers.
[26] Johnson also scored twice in Fulham's 4–1 win over Wisła Kraków on 4 November 2011, putting them on the brink of securing a place in the knockout stages of the UEFA Europa League.
[27] These goals were Johnson's seventh and eighth in the UEFA Europa League; he also scored against NSÍ Runavík, Crusaders, RNK Split, Twente and Odense.
[33] In August 2013, Johnson scored the winning goal in Queens Park Rangers' opening fixture of the Championship season against Sheffield Wednesday.
[citation needed] On 3 September 2014, Johnson signed a short-term contract with Crystal Palace on a free transfer, and was given some coaching responsibility with academy players.
[37] Johnson was first capped for England at U20 level, being selected in the team for the 1999 FIFA World Youth Championship alongside Stuart Taylor, Ashley Cole, Peter Crouch and Matthew Etherington.
[38] This subsequently hurried then England manager Sven-Göran Eriksson into giving Johnson his first call-up, to face the Netherlands on 9 February 2005, and he made his first international appearance in that match.
[citation needed] When Steve McClaren was installed as England coach, Johnson got further opportunities to play for his country in the UEFA Euro 2008 qualifiers.
