Chelsea have continued to spend big on new recruits, bringing in the likes of Nicolas Jackson and Christopher Nkunku to bolster their attacking unit, but are still being linked with another No.9. Gallas added on that pursuit: “Victor Osimhen to Chelsea? One player won't make the difference and change things around for Chelsea. Even if they buy one striker, you have to be sure the players around him have the quality to supply that striker. The squad is very young, so next year we may see an improvement in the team and they might compete for the Premier League. We have to see how many goals Nicolas Jackson will score, he has eight at the moment. If Jackson cannot reach 15 Premier League goals or more, then Chelsea need a top striker, because at the moment they don't have it. Nicolas Jackson has to prove now. If he doesn't reach between 15 and 20 Premier League goals, it will be difficult for him to keep a place in the team next season. Chelsea will sign a new striker. He has to take his opportunities now, whilst he has them, he needs to work very hard and become more consistent. That's what it takes to play at a big club like Chelsea.”
