The Portuguese has shot to the top of the club's wanted list after Xabi Alonso chose to stay at Bayer Leverkusen.
Tactically they're both different," Teixeira, now with Shanghai Shenhua, told Record when comparing both Amorim and Klopp.
They play differently, with Klopp in a four-man defense and Ruben in a three-man defense. Ruben has proved his worth and has done well in recent years, even though he's young.
He's already been a champion. They have had good results in the Champions League and Europa League. Sporting are playing well this year, but they were already playing well in previous years.
Ruben is gaining prestige so that he can then move on to a challenge like Liverpool. In a situation like I think happened with Chelsea, when they hired Mourinho and then Villas-Boas.
You can adapt well (in England) because it is a country where football works very well. In England everything is super organized and there is no confusion. Everything is prepared in advance so that it goes well.
But it is a difficult league for a coach to adapt to. You have to adapt to life, training and schedules. It's above all adapting to the game and the new reality, very different from what happens not only in Portugal, but in other countries.
Even Guardiola, when he arrived in the Premier League, conceded many goals on the counter-attack and had to adapt. The pace is different. You can have the game under control and from one moment to the next everything changes."
