I find it weird people care about the result in pre-season, even more strange that emotions are there after the second game against a fresher team. We could get thumped 4-0 for all i care, these games are just about minutes, trialing tactics, hyping up the players, findings weaknesses and then fixing with solutions. For example, matic and andreas are clearly useless, elanga looks like he may be grabbing a few more minutes next season, or maybe he is ready for a loan to develop further.
Also, DVB, Martial, Maguire,Shaw, Lindeloff, Bruno, Pogba, Fred, Mctominay, rashford, sancho etc, all first team guys, are still on holiday. I'm no Ole fan, but jheez, give the guy a break, he is freshening up the squad at the moment.
I remember a few years back, Benteke scored a tonne of goals during pre-season ( i think it was him), then during the actual season that mattered, he scored 2 or 3. I remember under Gaal we won every game, played some good football, beat madrid and barca (who were not as fresh as us) and then played terrible football for that season. City played a few games last season in pre-season, i think they lost some too, but smashed out the league.
I wouldn't worry, I would only concern yourself with making sure Varane is here, a RB, and a DM.
