Welbeck is well on track to surpass his career-best 10-goal campaign he managed last season in the Premier League. Remarkably, the veteran poacher has scored his six goals from just seven shots on target this season, highlighting his efficiency in front of goal, a trait Tuchel will take a lot of interest in.
England legend Alan Shearer believes the door is wide open for Welbeck to make a return to the national team, especially with there being no standout backup for Kane.
The Premier League icon told BBC Sport: "If you look at the forward options in Tuchel's last squad there aren't many obvious stand-ins for Harry Kane.
"Anthony Gordon, Jarrod Bowen, Bukayo Saka aren't going to fill that role and Ollie Watkins hasn't been firing for Aston Villa, so any English striker scoring goals in the Premier League is going to be talked about.
"It's seven years since Welbeck's last cap and he's 35 this month but Tuchel isn't worried about the future. His only focus is the six weeks of the World Cup so there's no reason why Welbeck couldn't be involved if he keeps scoring and stays injury free."
