Tammy Abraham is 22, Moise Kean is still a teenager.
Why are you so incessantly negative? He's played around 600 minutes of Premier League football under 3 different managers, in a country and language that is entirely new to him, in one of the toughest leagues about and in a team that has struggled for large parts of the season. He has a goal and 2 assists in the limited time he's had, no that's nothing remarkable but a goal contribution every ~200 mins he's been on the pitch in the league is far from "'kin pathetic". Try some positivity for a change, support the players, especially one who's still a teenager ffs.
