Celtic's Arne Engels is on the verge of a move to Crystal Palace, with the Eagles pushing to sign the midfielder for a £25m fee. The Scottish Premiership club are ready to sell Engels, who has been impressive for the Bhoys, if the South London club meet their asking price. Crystal Palace's new manager Pierre Sage is looking to strengthen his midfield ahead of next season, and Engels is seen as a key target. The 22-year-old has been in fine form for Celtic, and his sale would be a joint-record for the club. Engels is expected to leave Scotland in the coming months, with Nottingham Forest also interested in signing him. However, Crystal Palace are in the driving seat, and it remains to be seen if they will meet Celtic's asking price. The Eagles have a huge advantage in the transfer market, with their European status giving them an edge over other clubs. Sage has plenty of pressure to live up to expectations following the departure of Oliver Glasner, and signing Engels would be a major coup for the club. The midfielder's quality is undeniable, and he is ready to take the Premier League by storm. Celtic's demand for a record fee is justified, given Engels' impressive performances for the club. The transfer saga is set to continue, with Crystal Palace and Celtic negotiating the finer details of the deal. Engels' future is uncertain, but one thing is clear - he will not be playing for Celtic next season. The club's fans will be eager to see how the transfer saga unfolds, and whether Engels will indeed join Crystal Palace. The Eagles' midfield is in need of strengthening, and Engels would be a major addition to the squad. Sage will be hoping to complete the signing as soon as possible, to give his team the best chance of success next season.
