"I am here to win titles and am sure that we have the team and the coach to do it" said the Colombian.
Bayern Munich coach Carlo Ancelotti believes that James will make a big impact at the Bavarian Club. Speaking to reporters in Singapore on Monday, he said "James has a fantastic quality that can improve our level of play. I think he gives us something extra between the lines (attack and midfield), especially in terms of the final pass to the strikers."
Ancelotti's men sufferred an embarrasing 4-0 defeat to AC Milan on Saturday, but the Italian coach is hoping for an improved performance when they face current Premier League champions Chelsea on Tuesday.
"It is okay to make mistakes during this period as it is the pre-season. We use it to prepare well for the season, to improve the things that we need to improve," he said.
"Of course, no one wants to lose 4-0 so we hope for a better performance tomorrow. We are hoping for a good test and are focussed on a number of things - good play, defence, balance and attack," Ancelotti added.
"But I don't feel pressure. If I felt pressure now, I would be dead by the time the season started."
The Bayern coach believes Borussia Dortmund will challenge for the title in the umpcoming Bundesliga campaign, but is less sure about last season's surprise runners-up RB Leipzig.
Ancelotti said, "I expect the same teams to challenge us next season. Of course, Dortmund will be there and it will be interesting to see how Leipzig go now that they have Champions League involvement and they are not used to playing in this competition, combining domestic and European football."
