I'm surprised he's able to play, usually players that are loaned out cannot play against their parent clubs.
yeah, it is a practice to not let players play against parent club
Isn't that just an EPL of English FA thingy ? I'm not so sure If I've witnessed players not being allowed to play against their parent clubs in other league, I could be wrong because I don't think I pay much attention to it, I used to believe it's due prevent any form of potential match fixing debate or accusation, you can only imagine the kind of investigation that could warrant or bring up especially if it's in favor of the parents' club.
For instance imagine the infamous Leicester City center-back Wout Faes scoring two own goals within the space of seven minutes against Liverpool last season, if he were to be a Liverpool loaned player to Leicester City and there then that happened, I really doubt the British media, or any media would have gotten over the possibility of that being a match fixing scenario.
In my opinion, loaned players love to stick it to parent club and then not celebrating. Showing at the same time they are good enough to have played for parent club and respect if they get a chance to get back.
