“Of course, I will shake his hand. Why shouldn’t we shake hands? I don’t understand the question to him and I don’t understand the question to myself.
“We worked together in Barcelona for three years, we were opponents at other clubs but we are just professionals and we have a normal relationship.”
Like Mourinho, Guardiola looked irritated when asked about shaking hands with his rival.
“It’s a friendly game,” he said. “A really friendly game. Will I shake Jose’s hand? Of course,” he said.
“We are polite guys. Why not? Why should he not shake my hand? No reason why. He wants to win, I want to win, that’s all.”
He declined to comment on how his style and philosophy differs from Mourinho’s but admitted he expects United to be a better team under the Portuguese’s command.
“I’m pretty sure they will be stronger than the last years,” said Guardiola.
“With this manager and the good players they already have – I’m sure they are going to buy new payers – they will be a strong team.”
