I'm confident about Barcelona this season, unlike previous seasons where we complained about issues in various positions but this season both the coach and players can be trusted to achieve great success. Barcelona will surely win against Mallorca, regardless of how tough the match may be.
What makes you so confident in Barcelona? I haven't seen that much of a difference, apart from them having a full squad back (injured players have returned). There's been nothing more to their performance because it's preseason and they didn't play with the full squad at once...there were multiple subs at the same time. Until the season starts and they keep up the pace until mid-season, you can't really come to conclusions. Mallorca isn't a tough team for Barça anyway, so I don't know why you used the phrase '
how tough the match may be.'
Can you name one La Liga club currently in the same form as Barcelona? I don't think there is. I'm not judging Barcelona based on their preseason matches, but on their performance last season that they were the strongest team in La Liga and still have that quality now. This gives me confidence they'll perform well this season. The challenge for the La Liga title usually from Real Madrid and Barcelona, but I still see Real Madrid as the weaker team compared to Barcelona.
Concerning the Mallorca match, that i said it may be tough. I'm a real fan of Barcelona, and I'm not basing my opinion on highlights. Because last season despite Barcelona's victory over Mallorca, they gave us a tough time in both the first and second league matches, luckily we managed to win them.
