It would be stupid to give up PL just to test Tuanzebe. He is clearly a level below Lindelof/Maguire. They have not been great so far, but still we have only lost two PL games with them as CBs this season.
He needs to earn his spot. He gets minutes when we face weaker sides and if he performs well he get trusted with bigger matches. That’s how it works. He has been given time, but he has not performed well. He was, like everybody else, good vs PSG. In that match he had a clear task in a defence consisting of 8 defensive players. When he got the chance vs a weaker team, Basaksehir, he also got a bigger, more complex and more complicated task. He was not good enough to handle that task. Simple as that. He got the chance again against the same team, and did not really perform very well there either. All the talk that he would be the perfect partner for Maguire; in those two matches they seemed to be an awful pair. At the same time Lindelof, who most people think he’ll replace, has performed pretty well in the PL and we have four PL wins in a row and only one loss the last 7 games.
