Blackpool have been getting a little help from former Preston legend Graham Alexander.
McDonald explained: “Graham is a very good friend of mine and he wanted to come in and see how we work.
“We worked for a couple of days at the end of last week with him watching our training. He wanted to come to the game on Saturday. Having seen us work on the game plan, he wanted to see how it played out on Saturday.
“He will give us a bit of feedback on his thoughts, which is great.”
But McDonald insists their short-term association has already come to an end.
He said: “We aren’t bringing him to the club or anything like that.
“He’s been to Southampton and he’s been over to Spain to see how other people and coaches work.
“We will gladly have him around the club whenever he likes. I don’t think he’ll be back, though. He’s probably seen enough.”
Alexander witnessed Pool change their tactics to stifle Wigan’s attacking flair, a plan which worked perfectly on Saturday as Pool recorded back-to-back 1-0 wins.
