Guardiola believes City winning 20 games in succession could be the greatest achievement under his tenure – given the circumstances that surround it.
“It is so difficult," said Pep. “To have 20 wins in this period, I think this could be the greatest achievement we have done.
“It doesn't mean we have won the title of course, but in winter time in England, every three days a game, COVID-19 situation, injuries... winning, winning, winning shows strength, mentally.
“When you have a run of many, many victories, you have games like this. I remember against Brighton we suffered a lot for 20 minutes, Fulham as well.
“Every person who saw the game today knows it was really tough - the opponent is incredibly difficult.
“So a big compliment to West Ham - after 26 games they are in the Champions League positions and that is because of a lot of work."
He also said: “The important thing is we have been consistent in the last four seasons. Last season too. We finished second with decent points, in another season we would have been champions, but we faced an amazing opponent, so hats off to them.
“But we did not drop much. We won Carabao, semi-finals for FA Cup and quarter finals of Champions League.
“Every season is a new chapter - nothing counts in terms of what we have done in the past. It's a good lesson. I assure you right now, the game we will play on Tuesday will be similar to the game today.
“Tight result, we will suffer a lot, we need to be mentally strong and not give up for 95 minutes. That will help us win. If we don't, we will draw or lose."
