We won't and we don't need to. We MUST bring Vuskovic in this next season to get him club-trained, and he is absolutely good enough to be our 4th choice CB. In fact, I think there is a good chance that he would surpass Dragusin immediately, and possibly even Danso by the end of the season.
RCB - Danso, Dragusin, Gray
LCB - VdV, Vuskovic
RB - Porro, Spence
LB - Udogie, ???
Should we not get Europe next season, we can probably get away with just using Gray as a flex RB/CB, and playing Spence at LB with some games at RB.
I think we will buy the best available CB to replace Romero (assuming he wants to leave) who will also be an upgrade on Dragusin, providing we can find one so as to accommodate Vuskovic who, as this summer is when we officially buy and register him as a Spurs player will count as an overseas player for the next 2 seasons, and List B thereafter. With the money from selling both Romero and Dragusin we should be able to get the best available CB as a regular starter CB and have some cash over.
Enough out of europe, but if in europe we may need to weigh up if having Gray as a flexi CB/CM is enough, or whether we need to look at another flexi player or two - even Spence playing CB/RB/LB.
RCB - New CB, Danso, Gray flexi
LCB - VdV, Vuskovic (Danso can also play LCB I think)
Incidentally I think we have the right sort of numbers in squad so rather than buy players for squad I think we need to aim to bring in 2/3/4 players who are best quality who are wiling to come to Spurs so as to improve our first team and squad quality.
