Lokonga obviously has a lot of potential and is still young so I am sitting on the fence with him....however he didn't really add anything to the team this season. The issue with Tavares is due to Tierney being quite injury prone Tavares got a lot of minutes. That isn't a bad thing per say, but his performances on the whole were not up to scratch, he's not good enough for a team with ambition for a top 3/4 finish. He is not only raw, but lacks the basics of what is required. Don't forget Saka broke through as a full back and his performance level was high from start to finish, that's the standard of a top club.
Tavares may well improve, but I wouldn't feel comfortable having him in the team for important games next season.
Fair enough, but he hasn't been as bad as some seem to think - and I am hopeful that his consistency in defence will improve.
