Multiple reliable news outlets have reported that the race to sign Jesuran Rak-Sakyi is heating up, as reports indicate that Celtic have now officially submitted a bid for the player as they look to strengthen their squad ahead of the run-in. Talks are expected to continue over the coming days - with Crystal Palace said to be reluctant to let him go for a penny less than their valuation. While Celtic and Crystal Palace continue talks, no breakthrough has been reported. Rizespor, Lyon and Rangers reportedly may still have an interest, but currently the focus is on getting this deal across the line. So far this season, Celtic are steady at both ends (1.57 goals scored per game, 0.43 goals conceded per game). The role for Jesuran Rak-Sakyi would be to keep that balance while lifting performances across the pitch. Crystal Palace continue to be linked with Joe Gomez, David Brooks and Christoph Baumgartner while Celtic are also rumoured to be tracking Marcelo Saracchi, Michel Ange Balikwisha and Calvin Stengs.
