If i was Nuno i wouldn't see how i could say no myself. Much bigger club, better setup, just need a good manager and it pains me to say it but he is a good manager.
I think Arsenal will be a bit 'burned' on going for names. Emery was woeful and his signings god awful. Nuno and his team can spot a talent much better.
To be fair to Emery, last night was Arsenal's first loss at home this season and they had also only lost 3 away games before that, 2 of which were against Liverpool and Leicester.
Emery also signed Guendouzi (a class act bought for only £7m), Leno (very good 'keeper), Pepe (young and raw but clearly talented), Torreira (excellent player), Tierney (very highly regarded) and also bought in Ceballos (a fan favourite) on loan. Only Sokratis and arguably Luis (who I think gets a lot of unfair stick) seem below par signings.
