The Spain midfielder has hailed the signings of the two stars and feels the Catalans have improved this summer, but stresses that the former Arsenal man is not his successor
The Catalans secured the services of Cesc Fabregas from Arsenal and Alexis Sanchez from Udinese, and Xavi is confident that the duo both add something special to the team.
"The truth is that we have an amazing team and this year it is even stronger," Xavi was quoted as saying on Uefa.com.
"There are many players in the market but few that could have improved what Barcelona already have. Cesc and Alexis have improved the team, and so they have been welcomed. They will adapt easily because of their character, fitness, and the great team-mates around them.
"I am sure they will be playing very soon and they will adapt perfectly and show the class that they have shown in their teams."
Xavi stressed that he does not consider Fabregas to be his successor, adding that such a label would put pressure on the former Arsenal captain.
"I had a rough time when people were saying that I was [Pep] Guardiola's successor and I did not enjoy my first years, it was hard for me to adapt," he said.
"Cesc needs to be Cesc – he is a winner and we have different characteristics. I don't want anyone to be my successor and have to go through that pressure. Let him have his own personality and show what a great footballer he is."
Fabregas has impressed since his return to Camp Nou, scoring in the 2-0 European Supercup win over Porto and in the 5-0 La Liga thrashing of Villarreal on matchday one.
