Wickham arrived at Selhurst in the week leading up to the new 2015/16 season, and ended his first season by playing at Wembley for the first time in his career, netting against Watford in the FA Cup semi-final.
The striker arrived from Sunderland having scored 18 goals over the previous two seasons and played a starring role in their successful quest to stay in the Premier League during that time.
However he had begun his professional career at Ipswich Town where he made his debut aged just 16 years and 11 days to became the Tractor Boys’ youngest-ever player. He went on to gradually establish himself in their side and in 2010/11 he hit nine goals in 37 league appearances which led to him being named the Championship Young Player of the Year.
That form earned him his move to Wearside for a fee of £8 million and he would go on to play 91 times for Sunderland, scoring 15 goals - including five in three games to help his side miraculously avoid relegation at the end of the 2013/14 season, which included loan spells at Sheffield Wednesday and Leeds United.
After joining Palace Wickham had to wait until December to score his first goal for the club after suffering an injury early in his Eagles career, but did so by netting a penalty in Palace's 2-1 win against Stoke City before ending the season with six goals, including a powerful header in the FA Cup semi-final against Watford in April that booked his side's spot in the final which he featured in against Manchester United.
He had just started to find the goal trail again in 2016/17 before his campaign was cut short after he sustained a crucial knee ligament injury against Swansea City in November 2016, putting him out for the remainder of the season.
He has also starred for England at youth level, helping the Three Lions win the UEFA European Under-17 Championships in 2010 where he was also named Player of the Tournament, and appeared 17 times for the under-21s, scoring six times.
