After years of hoping he would rip opposition defences to shreds, Pep Guardiola has admitted he has to start trying to work out a way to stop Lionel Messi. On the prospect of facing the greatest player in Barcelona's history, Guardiola – the greatest coach the club has had – said: 'We will have to see what we can do in each of the two games and we will try to create the best defensive system possible to stop Messi. 'They are a wonderful team but so are we,' said the Bayern Munich boss. Pep Guardiola will be reintroduced to Barcelona in the Champions League semi-finals . The Bayern Munich coach must think of a way to stop the superb Lionel Messi next month . Guardiola goes back to Barcelona with the team now coached by Luis Enrique playing their best football since he left the club in 2012. 'It will be a very special game for me,' he said after the teams were drawn to face each other. 'It will also be special for Thiago [Alcantara] and for the rest of the coaching staff. I lived my whole life in Barcelona, it' s my home.' Guardiola nurtured Messi into the best player in the world while manager at the Nou Camp . Guardiola showed how much the club still means to him when alongside his father he watched them beat Manchester City in the last 16, cheering them on from the stands of the Nou  Camp. He did little to hide his appreciation for Messi that night and admitted that the four-times Ballon d'Or winner could punish Bayern if they are as sloppy as they were in the first leg against Porto in the quarter-finals. They went down 3-1 before hammering the Portuguese outfit 6-1 in Bavaria. He said: 'If we make the same mistakes then the tie will be all over in Barcelona.'
