Manchester United are continuing to show an interest in Bayern Munich attacker Thomas Muller, report German channel Sport1.
The Red Devils are claimed to be preparing an offer of 100 million Euros (£69.5 million), in an attempt to persuade Bayern to cash in.
Sport1 reported how United made an approach earlier this month for Muller, only for Bayern to tell them their proposed offer of £58 million was not enough.
They report that manager Louis van Gaal has personally been lobbying chief executive Ed Woodward to return with an improved bid for the German international, even during the ongoing US tour, and United are claimed to be ready to offer a five-year deal to Muller.
The Van Gaal factor
Muller is a player Manchester United boss Louis van Gaal knows very well, from his spell as Bayern Munich manager.
Van Gaal handed Muller his debut at Bayern, and the German international recently was quoted by ESPNpraising his impact on his career.
He said: "Van Gaal also had a huge effect on my development, I am very grateful to him -- he gave me great help and leadership, and he saw something in me as a forward where some others didn't."
Muller has a record of 120 goals and 105 assists in 304 appearances for Bayern Munich. This included 21 goals and 18 assists in 48 games last season.
He is currently on Bayern's pre-season tour of China, and if he joined, would link up with former club mate Bastian Schweinsteiger at Old Trafford.
