A serious blow this season was the disappearance of Conor Gallagher to Swansea City at the turn of the year. Now Cymru Ar-lein has explained some of the background to the decision: https://www.walesonline.co.uk/sport/football/transfer-news/chelsea-conor-gallagher-swansea-charlton-18541300?fbclid=IwAR0arS_ZfX4VGvvuiMH97yQu3JJ2yRPmIdiwOZy_p47qpMPUPxf5qvdhaFs
Gallagher reckons that Swansea get more of the ball than Charlton. It is evident that he is focused on his future career at Chelsea. It's another reminder that footballers, especially loan players, are employees and we shouldn't identify with them too strongly.
