Manchester City face a difficult night in Italy against Napoli.

A team like that, playing at home with the goalscorers that they have, are clearly dangerous. And Napoli will play double or quits on this game - they have to win.

I saw Napoli play at Manchester City and they made a real impression in their organisation and their use of counter-attacks.

They play like an Italian team inasmuch as they only attack three times per half, but when they are in and around the box they are remarkably efficient and they always finish well. They are very intelligent.

I think they can achieve something

There
are some similarities between Robin van Persie and Thierry Henry, but they have
a different way of playing.

Above all, Van Persie is a very good player, then
when we look at his stats we see he is also a goalscorer. He is in a group of
players who are creative and effective.

I
took the decision to play him through the middle because he doesn't have the
physical characteristics of a winger. Players who have exceptional technical
quality, as he does, should be played through the middle.

This
week we play Marseille, from whom we bought Robert Pires in 2000. Robert has a
lot of qualities as

I expect Tottenham's
Champions League tie with Real Madrid to be fairly even.

For me, each side has
a 50 per cent chance of winning the game, even if Real Madrid have a little bit
of a head start.

Madrid are the more
accomplished of the teams and their players have a lot of experience in European
competition.

For the first time in seven
years Madrid have qualified for the quarter-finals of the Champions League, yet
for Jose Mourinho and his team that won't be enough - they want to go on and win
the competition.

Madrid have greatly
improved in terms of their tactics and attitude this season,

It
is clear to me that Fernando Torres is suffering from a lack of efficiency at
the moment, but he can put that right against Manchester United.

The
Spaniard has yet to reach his optimum physical condition, so he cannot be
considered as the key player that he was when he played for Liverpool.

Moreover,
the forward is having to cope with the pressure of his transfer fee and has to
acclimatise himself to his new team and new strike partners.

Torres
will need time to impose himself at Chelsea; even when you have invested £50
million for a striker, you still need to be patient in waiting for

Have Schalke what it takes to beat Manchester United? Honestly, no.

I was asked who I wanted in the last 16 and I said Schalke. Schalke were the weakest side at that stage of the tournament and they still are.

I'm not saying Schalke are rubbish but it would be bizarre to see a team who are struggling in mid-table in their own domestic championship win the Champions League.

Schalke are being carried by Raul at the moment. He's a great player and he didn't go to Germany to retire quietly.

The question that we may have asked about Raul was whether he was finished physically. Personally, I thought

The Champions League semi-final between Real Madrid and Barcelona will be a contrast of styles.

One team will look to take the initiative while the other attempts to block them and launch counter-attacks. And when the attacking team becomes exhausted, they will be in real danger.

This is why I worry for Barcelona. The players cannot change their way of playing, which is a part of their identity. As soon as they lower their physical intensity, they will be exposed on the counter.

It is the pattern we saw in the Copa del Rey final at the Mestalla.

Madrid coach Jose Mourinho has a philosophy
