I really can't see any scenario where we have four first team central defenders fighting for two spots. Would love it, especially if it included mama.
I think it should be a really class cb coming in to partner matip, with lovren as backup and klavan as fourth choice. I can't make a judgement on gomez at cb as the only time i've seen him there was pre-season i think, maybe a cup game, but he looked pretty poor.
I generally subscribe to the old notion that you need two players for each position and two quality players at that. Our problem this season and going back quote a few seasons has been our defence, not our ability to score goals. Having a midfielder in Lucas slot into centre back or a pretty average veteran in Klavan being third choice for a side like Liverpool simply isn't going to cut it and it has cost us again this time around in our efforts to maintain a title challenge.
Should we make the Champions League then having those 4 as options would be fantastic and it would go so far in helping us challenge in all competitions. Matip, Lovren and Sakho all seem to pick up niggling injuries and who knows how long it'll take van Dijk to get back up to speed as he suffered a season-ending injury, so game time shouldn't be a problem and all would have a chance to stake a claim as being first choice.
Having 4 such options means that complacency shouldn't be an issue. Would Sakho want to piss about or underperform knowing he'd be at last chance saloon? van Dijk would be a new signing, he would be desperate to impress and get up and running after an injury. Lovren still divides opinion here and hasn't quite lived up to his price tag so he would want to improve, especially on the back of a new contract and Matip will have had a year to adjust to the league, country and whatnot and will himself want to show his earlier season form on a regular basis.
I don't mean it to sound very football managerish but it is something we haven't done for a while, have 4 quality options at the back. When was the last time? The complacency issue is so important across the whole back line. Milner is a thorough professional but he isn't getting dropped for Moreno unless he starts backheeling the ball into his own net on purpose. Clyne has more chance of being replaced by Alexander-Arnold but Nathaniel's form has been indifferent yet Klopp persists.
It's about quality, not numbers. We need more quality in key positions, if we continue to cut costs in defence then we will continue to ship goals. Shipping goals cost us the title 3 years ago, not a slip or a meltdown at Palace. It was conceding 50 goals over 38 games. This season we've conceded 40 already, out of the top 9 teams in the league only West Brom have a worse record with 41 goals against, so there isn't anything in it. It shows that our firepower up front has been the main reason getting us into the position we are in, if we could be more frugal at the back with better players to choose from then we'd surely have a better chance at maintaining a challenge and winning trophies going forward.
