Marchisio should be kept unless a very large offer comes in. i.e £25m. Whilst he isn’t guaranteed to start every game he is still a very good player, albeit not a great one. When he is not starting he is probably a first choice sub, if we sold him we would need a replacement and you don’t get a great deal for 15-20m these days. Most big clubs these days will have 5 or good/high quality centre mids.
