Pepe was not his choice, he wanted Zaha and got overruled. Saliba was a great buy but of course not really "for him" as he was a few years off having any role for the club. Torreira, Sokratis were Mislintat's work. He got there in the middle of an influence war and pretty much lost all his battles with the higher-ups.Utd fans say ETH spent too much money with 400m in 2 windows.
When he was at Arsenal. They spent over 200m in just over a year. Pepe was 80m of that. 30m for Saliba, Toreira and Tierney. Leno was 25m and Sokratis 16m. He also signed Gendouzi, Luiz and Martinelli for 6-10m. Then 2 or 3 free and loans.
Bit like ETH, spent the money, for the most part it just looks like it was spent badly.
He's a good manager if there's no drama behind the scenes, he was unlucky to arrive at the wrong time.
