The formation we used last year was a compromise IMO. We didn't have solid enough central midfielders to play only two, we didn't have enough quality on the wing to employ 'proper' touchline hugging wingers, and we lack a goal threat up front.
The Yak could be a good signing, but only if we get the right players in to support him. He doesn't work hard enough for 90 mins to be the focal point of a formation. If we get him, we need someone quick buzzing around him, which means two up front, which means playing a 4-4-2.
Som IMO, if we get The Yak, we also need to get a combative Savage-like cm, wingers x2, and an additional, quick striker.
Would Nugent and The Yak work? I can't see Emile and The Yak playing together, they would be too static.
