Pep Guardiola has left the door open for a renewed attempt to sign Alexis Sanchez after a £60million deal for the Arsenal star collapsed on deadline day. The two clubs agreed terms in August only for Arsenal to pull the plug when they failed to sign Monaco's Thomas Lemar as a replacement. Sanchez, who faces City at the Etihad on Sunday, will be a free agent in the summer but a January move to Pep Guardiola's side is not out of the question. Although Guardiola was reluctant to discuss the Chile international so close to the match, he admitted that he will continue to improve his squad where possible. 'The strikers we have are going to stay next season, hopefully,' he said. 'Add another player? Maybe. We are going to decide that. 'So I think next season we have to shake the team again a little. Not in terms like this season, where it was a lot because the average age was 28 or 29, now we are a young team.
