Regardless of how things go, the FA, the media and fans need to stick by him and this squad for now. It's a young manager with a young squad who will probably peak in 2022. So give him the Euro's and the next WC and see what he does with them. Even if we got a 5-0 hiding off Sweden, stick by him and this group.
Very few of this starting XI will be too old come 2022 and with the excellent youth teams he could be on to something. If we have to take our lumps even at the next Euro's no harm.
Pickford, Stones, McGuire, Sterling, Lingard, Rashford, Kane, Alli, Loftus-Cheek, TAA will all be at or closer to their peaks, with talents like the Sessegnon's, Foden, Sancho, Gomes, Lewis Cook and Chelsea's army of ridiculously talented youth all in their early 20's. There is huge potential in the set up. Stick to Southgate, stick to his style and give them time to achieve.
