I’m going to disagree on this one too I think.
I think the general point that he’s in decline is fair. But every transfer window we struggle to get players of real quality to sign for Celtic. No doubt some of that is money but it’s also the league and the country etc. So we make do with guys like Mulumbu.
Brown was excellent last night but hasn’t been great overall this season. I’d still say he’s probably been our third best midfielder though behind McGregor and Christie. An in-form Rogic would have been much better but Rogic has struggled for form for most of the season, bar that spell when Brown was injured. The same applies to Ntcham. Bitton, Kouassi and Mulumbu aren’t as good.
As long as he’s not on a fortune and we’re not going to be relying on him in every game I think he’s worth retaining.
