The Hammers previously confirmed, via their official website, that the 23-year-old had re-joined Charlton on loan for another season after previously spending his 2018/19 campaign with them.
Cullen played the full 90 minutes for Charlton on Saturday, with them beating Stoke City 3-1, and celebrated making his second debut for the London club on his personal Instagram.
“2nd debut and a win (tick), The lads were great and thanks for your support,” wrote the midfielder.
Cullen being happy with his Charlton debut then saw former Hammer, Konchesky, send him a six-word message in order to tell him to keep up the good work.
“Keep up the good work pal,” wrote the retired defender on his verified Instagram account.
Cullen did okay on his debut for Charlton on Saturday but didn’t really overly standout. The 23-year-old’s display achieved a rating of 6.61 on WhoScored, which reflects that he wasn’t particularly good or bad. However, it’s worth noting that Cullen was never sloppy in possession as 85.7% of his passes did find their mark (Source: WhoScored). The Hammers midfielder was given the chance to impress Manuel Pellegrini in pre-season after a successful loan spell in League One with Charlton last season and clearly didn’t do enough to convince the Hammers boss that he was ready for Premier League action. Yet that doesn’t mean he should throw in the towel on his Hammers’ career by any means. If Cullen can consistently deliver the goods in the Championship, which is only one level below the Premier League, he may still have a chance of fulfilling his potential at the London Stadium. This is the case even though the 23-year-old’s West Ham contract expires next summer. According to reliable Hammers source ExWHUEmployee, there’s a recall clause in the loan agreement between Charlton and the Hammers about Cullen, so who knows, he could be playing for Pellegrini from January onwards if he plays his cards right.
