Conor Gallagher struck twice to condemn his former club Crystal Palace to a damaging 3-1 defeat on Monday and keep Chelsea in the hunt for European football next season. 

The injury-ravaged Eagles were on course for a huge win in their battle to remain in the Premier League when Jefferson Lerma’s long-range strike opened the scoring. But Palace have won just three times in 19 games and were undone late on after Gallagher equalised within two minutes of the second half.
