Personally, I am comfortable with the club using Sarkic as Ruddy's replacement, Giles as Marcal's replacement and Morgan as Trincao's replacement. It is good to have young players that have proven themselves and toughed it out in lower Leagues in the squad. They will all provide good options as well as acting as guiding lights for other youngsters.
But Saiss and Moutinho are first team starters and their replacements need to be top class. Lage has also called for a new target man and he deserves to be supported to bring in his players.
The best way to let Bruno shape this squad is to let him bring in his own spine of the team and, as coincidence would have it, a new spine is exactly what we need, and have needed since Sevilla, anyway. New CB, new DMC, new AMC, new ST. The Club keep saying only genuine improvements to the first team will be bought and we need them in those four positions.
Speculation is what it is, but if we went something like Milenkovic, Palhinha, Sanches and Kalajdzic that would be perfect. Right age, right profile, right price.
What we definitely don't need is more flighty Portuguese wingers that will take a year to settle and stop the development of our current flighty Portuguese wingers.
