For much of the Premier League, Timo Werner represents an unfamiliar threat with the German international having played exclusively in the Bundesliga before signing for Chelsea this summer.
As much as Werner needs to acclimatise to the Premier League, so will opposition defenders have to understand his strengths and weaknesses to nullify the threat of the 24-year-old.
Outside of the internationals across the league, predominantly in an individual sense as opposed to a collective defensive unit, and those who have faced him in one-off European ties, Werner’s habits just won’t be fully recognised by the majority.
But for Southampton manager Ralph Hasenhuttl, when he sets his team strategy for Saturday’s encounter at Stamford Bridge, the Blues No11 will be the individual in Frank Lampard’s XI is he most familiar with.
Werner was just 20 when he became RB Leipzig’s record signing from Vfb Stuttgart, with Hasenhuttl taking over that summer and the striker going on to score 42 goals in 77 games under his management and broke into the Germany squad.
Reunited at Stamford Bridge on Saturday on opposite sides, Hasenhuttl is hoping his former protégé won’t be left smiling at full-time.
“I hope so yes [will get to speak to him] but hopefully not to congratulate him for a goal.
“He was fantastic for me in his first year, scored plenty of goals,” Hasenhuttl said.
“I have worked with a lot players and he is one of the quickest and he is really hard to defend against.
“He is getting a more complete striker now and is learning a lot. He is a good striker for Chelsea and he is only happy when he scores, so I hope he is unhappy after the game.”
Werner is yet to find the target for Chelsea in the Premier League, having scored against Tottenham in the League Cup, but has showed enough signs that once one falls, he will go on a consistent run.
