I think we 100% need 2 players who are good enough to play 1st team.
1 Striker who can play as a Lone Forward but also has the ability to play any of the attacking 3 positions. Basically an upgrade on N'Jie.
1) Lazcette 2) Batshuayi 3) Berehinio
A Central Midfielder who can play either of the deep Central Midfield Positions. That way we can rotate them with Dembele & Dier.
1) Schniederlin 2) Wittsell 3) Tielmans
If this is our squad going into next season I am confident we can challenge for the title again and compete in Europe and the Cups.
Lloris Vorm
Walker Trippier
Rose Davies
Alderwireld Vickers
Vertonghen Wimmer
Dier Tielmans
Dembele NB/RM/TC
Lamela Son
Alli AP/JO/HW
Eriksen Chadli
Kane Berehino
Dier can play RCB to avoid throwing Vickers in deep and Alli can come back to CM if you feel any of Bentaleb, Mason, Carroll are not up to it (my hope is Bentaleb gets back on track). One off Pritchard, Onomah or Winks should get an opportunity to prove themselves and it be great to see Onomah become the next break out player from the youth team.
If a top class winger becomes available like a Schurrle and the price is right you take him. Send one of the 3 AM's out on Loan or sell Chadli. If a good deal on a Right sided CB comes a long take him and send Vickers out. If you can find a better back up keeper to Lloris take him and sell Vorm. If a good deal for an experienced version of Dier who can play CB & DM take him and you look to cash out on 2/3 of Mason, Bentaleb or Carroll.
Given we hopefully should have CL football, much as I like Berahino I suspect we will be looking at targets like Batshuayi and Lacazette now.
