Smalling and Blind did a "great job" last season but as soon as they were put under pressure by half-decent opponents they conceded lots of goals. Righto.
No that is not what I am saying at all. It is common sense that when you play better teams, the defense will always concede a much higher possibility of conceding goals or chances created because great offense forces more defensive errors--which every defender makes in every game;thus, goals will be scored. When comparing the goals against record based on the quality of the opposition, which typically have a higher quality of offense the better the offense, the better the quality of opposition, the higher chances of goals scored. Secondly, we didn't concede that much goals against bigger teams compared to our rivals.
For example in the EPL we conceded 11 goals in 8 games against top 4 EPL teams(bit extreme to call the biggest teams in the Prem and Champs league, better than half decent aswell)
Tottenham conceded 11 goals 9 games against top 4 in all comps
Arsenal conceded 9 goals in 10 games against top 4 in all comps
Leciester conceded 13 in 8 against top 4 in all comps
God knows how many goals Man City got wrecked by, but you see my point. 1 point I might also add is that 6 of those goals came in 2 games where we made tactical errors-- Against Arsenal Van Gaal thought it would be a smart idea to press two of our slowest DMs in Carras and Basti up the pitch to man mark the oppositions central midfield which gave Ozil and Sanchez ample space to dominate-- and injuries-- against tottenham, right after TFM comes off we concede 3 straight goals thanks to piss poor defending from Darmian. Also, a large amount of goals that we conceded playing against bigger teams was from poor man marking on set pieces.
Van Gaal's safety-first football was based on the premise that while you have the ball your opponent can't hurt you, which in practice meant maintaining possession far from goal with a seemingly endless string passes between the back 4 and midfield. Mourinho's sides sit deep, soak up pressure and then look to hit the opponent on the break. Both strategies could be termed 'defensive' but the latter involves using defenders who can actually defend, rather than just pass it about a bit.
While you may be correct about the conservative set up by Van Gaal, it is not as if we are always dominating possession. On average we have 54 %possession most games, but any team that can play good offensive football can still kill us with less possession. For example, against Tottenham we had 54 possession throughout the whole game , so we should concede less chances right? Wrong. They killed us by 3 and we conceded 16 shots on target. Playing safety first football limits the opportunity of counter attacks, but it doesn't stop teams from scoring through buildup play, set pieces, and long balls.
Mourinho teams don't just require 2 CBs who can defend it requires the ENTIRE team to be able to defend well collectively as a team with everybody behind the ball working their socks off to win it off the opposition then to hit them on the counter.
I don't know who's available, but ideally the club should be looking for someone experienced.
Much easier said then done. Most experienced CBs--that actually have talent-- are in their prime and in much better situations in much better teams, then again we did sign Pogba so you never know.
