I never said they were separate and you only have to be good at one. I just tackled two points because a modern fullback has two sides to his game and you stated he was wasted at LB (in attack) and wasn't good enough defensively. So if I believe Sessegnon is good enough in attack, then the only reason to believe he's not good enough to be a LB is due to his defensive inability. So yes they are a tandem when evaluating a fullback. We have a need for a right winger. And Chong hasn't proven himself at first team level. On the other hand, Sessegnon has a lot of experience at LB. Fulham fans were bragging about how he can play all over the pitch last year. It's just that his attacking ability was so good that it was a waste for him to be a LB for Fulham. A better comparison is Bale rather than Chong. Difference is, Bale proved himself to be world class as an attacker. Sessegnon hasn't proven that yet so making him a LB isn't out of the question as it stands. Instead of looking at it as a waste of Sessegnon's ability, look at it as acquiring the best future attacking LB in the game. His twin brother is also a fullback but on the right side of defense. Bit similar to Varane. Signed at age 18 and he's only 25 right now. I hope we're in for him. Teams like Bayern are already starting to look toward the future and I feel we have a younger core of players compared to most big clubs at the moment.
