Real Madrid has better financial current condition than Barcelona after facing financial crisis more than last several season but Xavi Hernandez success won La Liga tittle last season. I agree with you how Barcelona's management putting Xavi Hernandez on huge pressure without giving much money for signing new players and management huge expected with Barcelona winning La Liga and UEFA Champion League tittle. Its main problem not comparison between how much money spending by management and their target keep impressive performance make Xavi Hernandez announced for leaving Barcelona next season.
I don't know for next manager will be success like Xavi without get much money for signing players but management huge target for winning La Liga trophy.
Comparing Madrid and Barcelona at this time is certainly not an ethical thing, because after all, the current conditions of the two teams are very different, especially in terms of finance, Barcelona's ability to compete in La Liga has actually ended when they get financial problems that even reportedly Barcelona have to pay off debts that reach up to 500 million euros at this time, And that's why if we compare Madrid and Barcelona today it's like earth and sky in my opinion.
I think Xavi's decision to leave Barcelona next season is the right decision after maybe he is not appreciated by the current management, Barcelona look too demanding even though they realize that their finances are very limited to be able to make the Barcelona squad better in the title race, now Xavi has managed to take Barcelona to the quarter-finals of the Champions League and with limited funds they budget So far, Xavi, of course, it has been quite a brilliant achievement and it may be very difficult if other coaches do like as Xavi is doing at Barcelona.
