To be honest I think Mirallas might have said to Martinez that he wants more opportunities to play centrally so that might be why Martinez is making noises about Mirallas as cover for up front. We still need a striker to cover Jelavic/Kone but with McGeady coming in it does seem like Mirallas might be slotted in where he's needed most across the front 4. It might even play into Martinez' transfer ideas because he might just be thinking that instead of getting an out and out striker he gets a Mirallas type of player in who can play up front but he's just as comfortable anywhere on the forward line.
That makes sense to me. Lets just for a second be optimistic...and I know its slim chances BUT if we have a chance to sign Lukaku on a permanent (we dont know yet and might be a pipe dream) we know he wants to play most games. Getting in another striker as backup that are quality will be extremely difficult as they would also want to play most games if they are quality. However...if we bring in a quality player that can play across the front 4 it opens up a lot of options to allow adequate game time to keep everyone happy. However we already have Mirallas who can play as a striker and have played as a striker for a few seasons at Olympiacos.
Thus McGeady enters the equation...all of a sudden we now have a good winger that can start...allowing Mirallas to start as Striker IF we need him in that position. Deulofeu we must also remember might be here for another season...giving us a lot of options on the wings now. However...IF Mirallas starts as Winger and we need to throw on a fresh striker we still need backup...but only backup. And it might mean that the striker we might sign will be a backup striker...BUT our main backup for starting incase of injury etc might be Mirallas. This changes as to what we might need as backup in the striker department maybe. And might free up finances (by saving of a expensive striker in this window) to bring in Lukaku on a permanent at the end of the season.
Once again...total speculation and possibly a pipe dream BUT just maybe it might be in our managers back of his head. Why did he say to Lukaku when Lukaku said he might consider staying IF we get CL that he must score the goals. Maybe I am reading too much into it all but here is hoping Lukaku is on our long term plan and thus we might ONLY get in a good backup striker but not a quality striker due to Mirallas that can fill into that position for now. OR maybe I am too tired this early morning to think rational...lol
