"He made 322 appearances for Celtic and 502 for Liverpool", I'd add "During his career," ahead of this as it reads pretty number heavy from the start.
"also a record, held jointly with Denis Law", I'd drop this mention of Law, switch to "also a joint-record". Law is already mentioned as the joint record holder in the third paragraph and this sentence is a bit long, so this will trim it down a little.
Scotland are already linked in the first paragraph so there's no need to link again in the second. A few more doubles in Director of Football and Scottish League Cup in the third and League Cup in the fourth.
"Newcastle finished runners-up in the Premier League", finished as?
There are two mentions of Anfield in the last sentence but the second is linked, not the first?
Refs 8 and 9 are used in text so there's no need to keep them in the lead.
I'm a bit confused about the Cumbernauld United info. In the infobox, it states he was a youth player there before joining Celtic. In the text it states he joined the club on loan as a professional? The year of signing his pro contract with Celtic also doesn't tally with the infobox.
He signed the contract in 1967 but played with the reserves until pretty much 1971, However I'm not sure whether playing for the reserves while making occasional first team appearances counts as professional or not. REDMAN 2019 (talk) 11:57, 26 May 2020 (UTC)[reply]
Refs 12 and 13 are the wrong way round on the joiner sentence. Refs should be in numerical order.
"He played with the reserves throughout the 1968–69 season, but only scored four goals in 17 games. The following season, he moved into midfield, which saw his performances improve", this is extremely close paraphrasing to the LFC History source.
"during season 1969–70", I don't think we would refer to a season in this reverse format.
"The reserves, however, benefited from his goalscoring talent from midfield...", again this is pretty much word for word from the source.
"He also made some good long-term signings like Gary Speed and Shay Given", this is unsourced and reads like someone added it in response to the preceding criticism of signings.
Avoid shouting in ref titles, even if the ref itself does, per WP:ALLCAPS.
Refs 13 and 45 need an author.
Refs 16 and 30 are the same.
Why is Liverweb a reliable source?
Refs 18, 31, 35 has expired.
Ref 36 has no real publishing info. Is the site reliable?
Ref 40 needs an accessdate.
That's the first 40 refs covered, you can grasp the rest from that. Ensure refs are fully formatted and contain all available info.
A bit on the fence over this one, but I'm going to quickfail for now I'm afraid. The biggest problem is the sourcing, which is sketchy at best in some places, and no article should be coming to GAN with outstanding cn tags really. The Liverpool section is a little short perhaps also, three paragraphs for over 500 games. There's just a bit too much to cover in a single review, but with these changes, it'll be in much better shape. If you have any questions, please feel free to drop me a message.
