Pass and move players with decent technique like Maxi won't exactly be ushered out the door. However, I can't see Brendan assuring anyone of more playing time, especially someone who has a lot of competition for places. If Maxi gets offered first team football somewhere else, I don't see him staying.
Additionally, with no disrespect to him, he isn't anything overly special anymore. Just seems that way because he was actually able to finish a decent percentage of his chances over the last 2 seasons while our other players couldn't. He also kept his passing and positional play up to scratch. A player like that isn't too hard to find around Europe these days, hell we probably have one or two on our books as it is.
