He still has a big part to play for this club. Personally, I'd be giving him another contract. I know he is starting to pick up a few niggles, but as the old saying goes - Form is temporary, Class is Permeant. And Bobby has class in spades. I get the feeling he wasn't always 100% fit last season. At peak fitness, he is still a class act. If Nunez comes in and Mane goes to Munich, Bobby will still be required if Nunez doesn't hit the ground running and with the amount of games we could play, rotation will be a must. Plus he offers things that neither Nunez or Jota do. His ability to drop deeper into midfield and link play with the other forwards is something that is unique.
I still rate Bobby so highly and by the sounds of what he has been saying, he wants to stay. He has a few fellow Brazilians to socialize with and he knows the club, the area and still has the best song!
