The league just started, so it is very early to talk about who will be the top scorer in La Liga, Robert Lewandowski will surely be in the competition for top scorer in the league, but i am not certain about Jude Bellingham, i know that he has scored four goals for Madrid in only three games, but he is a midfielder and i believe that after many games, the attackers in La Liga will score more goals that he will do, but it is possible that he will be amongst the top 10 in the list of topscorers.
You're absolutely right, Robert Lewandowski is a top goal scorer for the blaugrana, he will definitely contend for highest goal scorer this new season, the league is early to predict who will win, let's hold and watch out the potential players that would be consistent in goal scoring. Adding Jude Bellingham to the lists for goals, his chances are slimmed, despite netting crucial goals for Real Madrid, he's a midfielder and his roles are not open to goal scoring. I'm pretty sure Barcelona and Real Madrid will be pre-eminent competitors for La liga title this season.
Bellingham is an outstanding midfielder that has the quality of a striker and a midfielder,which makes him more superb and unpredictable. For Lewandoski,he just scored his first goal today and there are no doubts that he has broken the deadlock and will continue scoring more goals.
On the other hand,don't you think that all eyes and attention is on Lewandoski as he is a magnificent striker that will draw all attention to himself and for this reason,any club that Barcelona is playing will have two or three men to mack him. But Bellingham is a midfielder which people wouldn't put much attention on because he is not always at the striking position but instead he always come from behind to net the post. This will give him bigger opportunity to score more goals since he isn't the center of attraction. Although,I accept the fact that it is too early to talk about who will be the highest goal scorer.
