Jobe Bellingham needs to get to a point where he’s properly consistent for Borussia Dortmund before he’s called up by England.That is the opinion of European football expert Andy Brassell, who believes errors in big games have kept the younger brother of Jude in the Three Lions’ Under-21 squad.Jobe will have ambitions of joining brother Jude in the senior England squadGettyJobe has featured in all four of Dortmund’s Bundesliga games this season, playing 90 minutes in each of the first three matches.He came off the bench to assist the club’s winner in the 1-0 victory over Stuttgart that moved BVB two points clear of Bayern Munich.His form led to reports that the 21-year-old was in serious contention to earn a senior England call-up in Thomas Tuchel’s September squad.However, the younger Bellingham is remaining in the U21 ranks for now despite his upturn in form during his second season in Germany.How close is Jobe Bellingham to senior England call-up?Brassell explained to talkSPORT.com: “I think it’s still a bit uneven. “I saw him in the Franz Beckenbauer Super Cup the week before the start of the season [a 2-1 defeat to Bayern Munich].“He had bits during that game when he was great and he had other bits of it where he looked like he was drowning. “Against the likes of [Michael] Olise, it was really hard for him.“Certainly, his turning the ball over in the run-up to the second goal is something that had already been flagged in that game.”Jobe remains an integral part of Lee Carsley’s U21 sideGetty“He’s been really improved in the Bundesliga since then,” Brassell continued on the former Sunderland star.“I think there’s something there; there’s no doubt about that, but I also feel it’s better conditions under which for him to develop this season.“They do have more options, they do have more legs in midfield. “Joey Veerman has come in from PSV, and there are people around Dortmund who think he will supplant Jobe Bellinam and Jobe will find himself on the bench. I don’t think it’s that simple. “I think Veerman, despite being older, is someone who is developing in terms of a higher league as well.“I think that will be quite tough for him and that will take time. They can take the pressure off each other a little bit.”Jobe Bellingham has played a key part of Dortmund topping the Bundesliga after four roundsGetty“What we have is a Dortmund side that’s faster, stronger, more athletic, and he plays into absolutely all of that.”‘Enough errors in big games’Jobe had a baptism of fire after completing a £31million switch to Dortmund after helping Sunderland seal Premier League promotion.He initially struggled to cement his spot in the starting XI and manager Niko Kovac claimed he wasn’t ‘doing himself any favours’.Off-field struggles were part of that, with Jobe’s father, Mark, holding a heated discussion with the club’s former sporting director, Sebastien Kehl, on the opening day of last season.Bellingham, who was then linked with a loan move away, ultimately stayed put and has battled back to earn his manager’s trust.“He’s very much a Niko Kovac type of player,” Brassell added to talkSPORT.“But I think there are enough errors in big games that it feels to me that for a while, I don’t think we can start talking about England yet; he needs to get to a point where he’s properly consistent for Dortmund. “And at the moment we would be rewarding potential rather than production, I think.”
