After struggling with injuries throughout the 2017/18 campaign, Dreher suffered again this season but has recently been edging his way back into regular football.
The central midfielder enjoyed a fine 2015/16 as he came through the academy side to become a regular in the development team despite being only 17, and was named on the first-team bench for the Premier League game at Manchester United in April 2016.
The following month he won the club's Under-18 Player of the Year, and played for the first-team in pre-season. He was once again named on the bench for the Eagles' trip to Middlesbrough in September, but then injuries plagued his progression over the following 18 months.
