As for the premier league title i think Pep should better forget about it and focus on the Champions League where the have been doing excellently well.
Why do you think Pep should forget about Premier League? Or is it because Arsenal is already ahead of them with 5 points or what? The Premier League title is still between Arsenal and Manchester city, the gap between the two clubs is kind of close, Manchester City and easily cover it up, we know Arsenal is really in form that those not mean they won't lose any match, we know the Premier League winner will be between Arsenal and Manchester city, but nobody can predict the winner yet. I still have the feelings that Manchester City will be the one to win the Premier League.
Yes, I think Man City is still focused on the EPL even though Arteta's squad is strong this season. Arteta has found the ideal formation with players that suit his tactical needs, a combination of old, new, young and mature players in all positions besides that Arteta is also getting more mature in concocting tactics on the field.
However, Arsenal always have the same problem as Tottenham, namely consistency which is problematic at the end of the season. I'm worried that at the end of the season Arsenal will not play well again and will end up in 2nd position. Arsenal should not be happy with a 5-point lead because it's not too far away.
