Inter boss Luciano Spalletti still expects they will advance if they beat PSV because Barca are so formidable at home. "Of course, they have unbelievable players and it'll be so tough - but one thing we have is our belief and faith we can win". "His contribution is fantastic for the team in a period we need this type of performance". To arrive in that way in Barcelona we need to manage and we need to rotate the squad.
The two city rivals go head to head at the Emirates on Sunday afternoon, live on Sky Sports Premier League, separated by just three points in the table.

Heading into the match on the back of a five-game winning run in all competitions, Tottenham had some wind in their sails as they went in search of an early breakthrough. But of course it will be so hard and we need to focus now on Sunday - another derby against Arsenal.
Given the physical demands on his players, Pochettino has suggested a rule change that would allow him to repeatedly introduce and substitute players throughout a match.
"The pressure is on Arsenal to perform and win the game - if Arsenal do not win this game, you are going to go away from here saying, 'Tottenham are just getting away from Arsenal'".
Apart from Mesut Ozil and Pierre-Emerick Aubameyang, the rest of the team is made up of Spurs players.
