I know he won't come cheap but I rather have Tyler Dibling over Muani - even if Dibling may cost more. True, he's still young at 19, and he may have been over-hyped, but he is worthy the risk I reckon. Maybe a swap deal involving Johnson + cash (well, I doubt that either Soton nor BJ would be keen though)-
Moore and Dibling could be Spurs' WF for 10+ years to come.
I thinik Muani is a good player but I don't think he is what Spurs need. Yes, he can play wide on both sides and as a CF, but he is mainly a WLF, which Spurs have plenty of right now, in Son, Yang, Werner, Odobert, Moore, Johnson, Solomon. Yes, Werner is on loan, Son is getting "old", Solomon is out on loan, and Yang, Moore and Moore are unproven...but they are still Spurs players and taking up places in the Spurs squad.
