Good morning African,
starting 11 & instead of who - At the moment I think he is slightly behind others in terms of the pre season he has had, so without being the coach and able to see where he is compared to others, fitness and form wise(on training pitch), probably not at the moment...thinking ahead if everyone's sharp, then yes he would make my starting 11.....
---Kane---
---Lamela--- ---Njie---
---Eriksen---
To explain...yes I would play Lamela as along with Eriksen, always basically especially at home as I believe they are our most creative players, I would want Lamela to come inside and play the supporting striker role making a link between Kane and Eriksen, defensively I would want him to track the opposition full back as well so quite a job. Now while I think that Eriksen, Lamela & Kane can all link up well I have put Njie in there and taken out Chadli, reason being Njie provides the pace to our attack the others dont have, In all honesty I cant vouch for Njie has havent seen him play, Not being harsh on Chadli who chips in with goals but he would miss out I suppose, so to clarify a winger with pace on one side, Lamela cutting in getting close to Kane on the other and Eriksen play the no 10 role being the link between cm's and atttack.
Impact player - difficult question to answer because it depends on the circumstances and performances of others, but yes I would bring him on to chase a deficit as I rate him but in terms of player style, no I dont think he would be our best imapct player from the bench, if we are chasing a goal then I would want another striker, or some directness/pace against tired legs if Njie was on the bench. As above I would start him and would depend more on others to impact things from the subs bench if things are not going well for us. I think your question is...do you trust him??? its obvious my answer is yes.
Trying to control a lead - No Erik would not be the first name that springs to mind if I wanted to shore things up...he is an offensive player, but again it depends on the circumstances of the match...as in which area of the pitch are we losing a battle.
Both the above questions relate to the clubs failure of going into two competitive matches with only Kane as a recognized striker, This is not Lamela's fault, and in some ways he drew the short straw replacing Kane last week...but that does not excuse his level of peformance against Stoke that wat quite clearly below par.
Hope that answers your questions ok, I need to get a bowl of porridge now.
