Contributions are good, but are they reliable? For a season? Neither are. And it's been the case for 3 years. Losing Kompany, and then Laporte has hurt us but we genuinely have 2 recognised centre halves who only performed well together 2 years ago, times gone. Football moves fast, you can't hold on to form nostalgia for long, have to show your worth and ability. Neither have improved in 3 years, and unfortunately with the fixture run coming up in November/December, we may well struggle more unless both somehow step up big time.
